Detection of occult lymph node metastases in esophageal cancer by minimally invasive staging combined with molecular diagnostic techniques. (1/3372)

BACKGROUND AND OBJECTIVES: Lymph node metastases are the most important prognostic factor in patients with esophageal cancer. Histologic examination misses micrometastases in up to 20% of lymph nodes evaluated. In addition, non-invasive imaging modalities are not sensitive enough to detect small lymph nodes metastases. The objective of this study was to investigate the use of reverse transcriptase-polymerase chain reaction (RT-PCR) of messenger RNA (mRNA) for carcinoembryonic antigen (CEA) to increase the detection of micrometastases in lymph nodes from patients with esophageal cancer. METHODS: RT-PCR of CEA mRNA was performed in lymph nodes from patients with malignant and benign esophageal disease. Each specimen was examined histopathologically and by RT-PCR and the results were compared. RESULTS: Metastases were present in 29 of 60 (48%) lymph nodes sample by minimally invasive staging from 13 patients with esophageal cancer when examined histopathologically. RT-PCR identified nodal metastases in 46 of these 60 (77%) samples. RT-PCR detected CEA mRNA in all 29 histologically positive samples and in 17 histologically negative lymph nodes. All lymph nodes from patients with benign disease (n = 15) were negative both histopathologically and by RT-PCR. The stage of two patients was reclassified based on the RT-PCR results, which identified lymph node spread undetected histopathologically. Both of these patients developed recurrent disease after resection of the primary tumor. CONCLUSIONS: RT-PCR is more sensitive than histologic examination in the detection of lymph node metastases in esophageal cancer and can lead to diagnosis of a more advanced stage in some patients. The combination of minimally invasive surgical techniques in combination with new molecular diagnostic techniques may improve our ability to stage cancer patients.  (+info)

Medullary thyroid carcinoma with multiple hepatic metastases: treatment with transcatheter arterial embolization and percutaneous ethanol injection. (2/3372)

A 54-year-old man with medullary thyroid carcinoma in the thyroid gland was unable to undergo total thyroidectomy because the tumor had invaded the mediastinum. Radiation therapy and chemotherapy were given. Seven years later, intractable diarrhea and abdominal pain appeared, and computed tomography demonstrated hypervascular tumors in the thyroid gland and in the liver. The tumors were successfully treated with percutaneous ethanol injection to a lesion in the thyroid gland and transcatheter arterial embolization followed by percutaneous ethanol injection to tumors in the liver. Transcatheter arterial embolization and percutaneous ethanol injection may be valuable in treating medullary thyroid carcinoma.  (+info)

The intrarenal vascular lesions associated with primary antiphospholipid syndrome. (3/3372)

Even 10 yr after the identification of the antiphospholipid syndrome (APS), renal involvement in the course of APS is still relatively unrecognized, and is probably underestimated. The association of anticardiolipin antibodies and/or lupus anticoagulant with the development of a vaso-occlusive process involving numerous organs is now confirmed. In a multicenter study, 16 cases of "primary" APS (PAPS) were found and followed for 5 yr or more, all with renal biopsy. In all 16 cases of PAPS, there was a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries (12 patients), recanalizing thrombi in arteries and arterioles (six patients), and focal cortical atrophy (10 patients). In combination, these led to progressive destruction of the kidney, accelerated by acute glomerular and arteriolar microangiopathy in five patients. Focal cortical atrophy is a distinctive lesion, present in 10 biopsies, and likely represents the histologic and functional renal analogue to the multiple cerebral infarcts detected on imaging studies. The clinical hallmark of this vascular nephropathy in PAPS is systemic hypertension, only variably associated with renal insufficiency, proteinuria, or hematuria. The ensemble of histologic renal lesions defined in this study should aid in the separation of the lesions found in cases of secondary APS, especially systemic lupus erythematosus, into those lesions related to APS and those related to the underlying disease.  (+info)

Nodular glomerulosclerosis with deposition of monoclonal immunoglobulin heavy chains lacking C(H)1. (4/3372)

The objective of this study was to further characterize the clinical and immunopathologic features of heavy chain deposition disease (HCDD), a recently described entity. Four patients were diagnosed as having HCDD on a kidney biopsy. All presented with nodular glomerulosclerosis with deposition of gamma1 heavy chains lacking CH1 epitopes, but without light chains. Two different patterns were observed in the serum. First, patients 1 and 2 had a circulating monoclonal IgGlambda containing a short gamma1 heavy chain lacking CH1 epitopes, with an apparent molecular weight of 40 kD consistent with a complete CH1 deletion. Biosynthetic experiments also showed that the deleted heavy chain was produced in excess compared with light chains, and was secreted in vitro together with half Ig molecules, although these abnormal components were not detected by Western blot analysis of whole serum. Second, patients 3 and 4 had a circulating monoclonal IgG1lambda with an apparently normal, nondeleted heavy chain subunit, but serum fractionation followed by immunoblotting revealed an isolated monoclonal gamma1 chain lacking CH1 epitopes. These data strongly suggest that renal deposition of a CH1-deleted heavy chain circulating in low amounts in the serum as a free unassembled subunit is a major feature of HCDD. The CH1 deletion is most likely responsible for the premature secretion in blood of the heavy chain by a clone of plasma cells.  (+info)

Angiotensin II receptor type 1 gene expression in human glomerulonephritis and diabetes mellitus. (5/3372)

The renin-angiotensin system plays an important role in the progression of chronic renal disease. Although the expression of renin and angiotensin-converting enzyme in experimental and human renal disease has been well characterized, no information is available regarding human angiotensin type 1 (AT1) receptor expression. The net effect of renin depends on AT1 receptor expression, among other factors. Receptor expression was determined in renal biopsy samples (including all tissue components) and isolated glomeruli from patients with glomerulonephritis (GN) or diabetic nephropathy (non-insulin-dependent diabetes mellitus). Biopsy samples and isolated glomeruli from tumor-free tissue from tumor nephrectomies served as controls. Human AT1 receptor gene expression was determined by quantitative reverse transcription-PCR, using an AT1 receptor deletion mutant as the internal standard. In whole biopsy samples from 37 patients with various types of GN, AT1 receptor mRNA levels were lower, compared with nine control biopsy samples (P < 0.001). AT1 receptor mRNA levels were also significantly lower (P < 0.001) in eight samples from patients with diabetic nephropathy. In microdissected glomeruli, AT1 receptor gene expression was significantly lower in samples from patients (n = 22) with various types of GN, compared with 12 microdissected tumor nephrectomy control samples (P < 0.0023). It is concluded that AT1 receptor mRNA expression is low in glomeruli of patients with chronic renal disease. This may reflect a regulatory response to (inappropriately) high intrarenal angiotensin II concentrations.  (+info)

Bone marrow scintigraphy using technetium-99m antigranulocyte antibody in malignant lymphomas. (6/3372)

BACKGROUND: The purpose of this study was to elucidate the clinical reliability of immunoscintigraphy (IS) to detect infiltration of the bone marrow in patients with malignant lymphoma. PATIENTS AND METHODS: Whole body IS was performed in 103 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) using Tc-99m labelled anti-NCA-95 which allows visualization of the granulopoietic bone marrow. Of these, 52% were studied prior to any therapy. Findings were compared to posterior iliac crest biopsy as well as MRI and/or follow-up examination. Criteria of marrow infiltration were a positive biopsy, positive follow-up, or positive results of MRI. RESULTS: Comparison of IS and biospy revealed concordant findings in 69 and discordant findings in 34 of 103 patients. Of the 34 patients with discordant results, IS showed lesions suspicious of bone marrow infiltration in 29 patients despite normal biopsy findings. When follow-up and additional examinations were taken into consideration, 10 patients remained with probably false positive and five with false negative IS findings. IS proved to be highly sensitive and specific in patients with HD (100% and 84%, respectively) and high-grade NHL (93% and 84%, respectively). Moderate sensitivity (60%) was found in low-grade NHL. This was possibly due to false negative IS in three to five patients with chemotherapy in contrast to one of five false negative results in patients without chemotherapy. CONCLUSION: Bone marrow scintigraphy using antigranulocyte antibodies is highly sensitive in HD and high-grade NHL. Positive findings in IS subsequent to a negative biopsy should be followed by guided re-biopsy or MRI.  (+info)

Benzodiazepine premedication: can it improve outcome in patients undergoing breast biopsy procedures? (7/3372)

BACKGROUND: Women awaiting needle-guided breast biopsy procedures may experience high anxiety levels. A randomized, double-blind, placebo-controlled study was designed to evaluate the ability of midazolam and diazepam (in a lipid emulsion [Dizac]) to improve patient comfort during needle localization and breast biopsy procedures. METHODS: Ninety women received two consecutive doses of a study medication, one before the mammographic needle localization and a second before entering the operating room. Patients were assigned randomly to receive saline, 2.0 ml intravenously, at the two time points; midazolam, 1.0 mg intravenously and 2.0 mg intravenously; or diazepam emulsion, 2.0 mg intravenously and 5.0 mg intravenously, respectively. Patients assessed their anxiety levels before the needle localization, before entering the operating room, and on arrival in the operating room. Patients completed a questionnaire evaluating their perioperative experience at the time of discharge. RESULTS: Patient satisfaction during needle localization was significantly improved in both benzodiazepine treatment groups (vs. saline). The incidence of moderate-to-severe discomfort during needle localization was lower in the midazolam (20%) and diazepam emulsion (6%) groups compared with the saline group (70%) (P<0.05). The preoperative visual analogue scale anxiety scores were similar in all three groups. In the operating room, however, anxiety scores were 55% and 68% lower after midazolam (21+/-19) and diazepam emulsion (15+/-14) compared with saline (46+/-28). Finally, there was no difference in the time to achieve home-readiness or actual discharge time among the three groups. CONCLUSIONS: Premedication with midazolam or diazepam emulsion improved patients' comfort during needle localization procedures and significantly reduced intraoperative anxiety levels before breast biopsy procedures without prolonging discharge times. Use of diazepam emulsion may be an effective alternative to midazolam in this population.  (+info)

Evaluation of "solitary" thyroid nodules in a community practice: a managed care approach. (8/3372)

Evaluation of thyroid nodules remains a challenge for primary care physicians. To include or exclude the presence of malignancy in a thyroid nodule, radioisotope scan, ultrasound, and fine-needle aspiration biopsy of the thyroid generally are used. The objectives of this study were to determine the utility and cost effectiveness of fine-needle aspiration biopsy of solitary thyroid nodules in a community setting; to compare the cost of fine-needle aspiration biopsy with that of radioisotope scan and ultrasound; and to determine whether the practice of obtaining radioisotope scans and ultrasound has changed in the 1990s compared with the 1980s. Patients were referred by community physicians to university-based endocrinologists for evaluation of thyroid nodules. Many of the patients had previously undergone radioisotope scans and ultrasound scans at the discretion of their primary care physicians. All patients underwent fine-needle aspiration biopsy. The biopsy results were evaluated prospectively, and the practice of community physicians' obtaining radioisotope scans and ultrasound scans was compared for the 1980s and 1990s. Eighty-three patients underwent 104 biopsies. In 20 biopsies the specimens were inadequate; the others showed 70 benign, 9 suspicious, and 4 malignant lesions. All four patients with biopsy findings read as malignant were found to have malignant growth at surgical procedures. Two benign biopsy findings were false-negative results. Malignant growth was correctly diagnosed later for one patient at a second biopsy and for the other because of growth of the nodule. The cost of 104 biopsies was $20,800. The cost of radioisotope scans was $22,400, and the cost of ultrasound scans was $10,640. The frequency of obtaining radioisotope scans (84.5% vs 77%) and ultrasound scans (65% vs 45%) was slightly higher in the 1990s compared with the 1980s. Fine-needle aspiration biopsy is a safe and cost effective initial evaluation modality for smaller community-based centers, as it is at large tertiary centers. The cost incurred ($33,040) in obtaining the radioisotope scans and ultrasound scans could have been saved if fine-needle aspiration biopsy had been used as the initial diagnostic procedure for evaluation of these nodules. Although radioisotope scan and ultrasound scan are of little diagnostic help in the evaluation of thyroid nodules, they continued to be obtained at a high frequency during the last decade.  (+info)

To evaluate the value of CT-guided percutaneous needle biopsy of bone in the diagnosis of lymphomas based on PET/CT results. A retrospective analysis of the records of all patients with percutaneous bone biopsies based on PET/CT results and a final diagnosis of lymphoma between January 2012 and August 2017 was performed. Thirty-one patients were included in this study. The success and complication rates were assessed. The mean age of the 31 patients was 46.6 ± 21.2 years, and there were 16 men and 15 women. A definite diagnosis and accurate histological subtype were obtained in 26 patients, for a success rate of 84%. The most common subtype was diffuse large B cell lymphoma (n = 18). The remaining subtypes included three cases of marginal-zone lymphoma, two cases of follicular lymphoma, one case of Hodgkins lymphoma, one case of peripheral T cell lymphoma, and one case of B cell lymphoblastic lymphoma. No serious complications occurred in any of the patients. CT-guided needle biopsy based on PET/CT
Background. Current recommendations for spinal tuberculosis (TB) not requiring open surgery include core needle biopsy to confirm TB and determine drug sensitivity. International figures show the positive culture yield from core needle biopsies is 50 - 83%. Objectives.

We sought to determine if confocal fluorescence microscopy provides sufficient resolution to evaluate specimen adequacy by comparing invasive tumor cellularity estimated from standard histologic images to invasive tumor cellularity estimated from confocal images of breast core needle biopsy specimens. Grayscale confocal fluorescence images of breast core needle biopsy specimens were acquired following proflavine application. A breast-dedicated pathologist evaluated invasive tumor cellularity in histologic images with hematoxylin and eosin staining and in grayscale and false-colored confocal images of cores. Agreement between cellularity estimates was quantified using a kappa coefficient. 23 cores from 23 patients with suspected inflammatory breast carcinoma were imaged. Confocal images were acquired in an average of less than 2 ...

Abstract. Background: The optimal treatment of flat epithelial atypia (FEA) found on breast core needle biopsy (CNB) is controversial. We performed a retrospective review of our institutional experience with FEA to determine if excisional biopsy may be deferred.. Methods: Surgical records from 2009 to 2012 were reviewed for FEA diagnosis. After exclusion for concomitant lesions, CNBs of pure FEA were classified using a previously agreed upon descriptor of "focal" versus "prominent". Data was analyzed with the Fishers Exact and Student-t test as appropriate.. Results: Of 71 CNBs evaluated, pure FEA was identified on 27 CNBs. Final excisional biopsy was benign in 24 of 27 cases (88%) with associated ductal carcinoma in-situ (DCIS) in 3 of 27 cases (11%). Eighteen of 27 (67%) CNBs were classified as focal while 9 (33%) were described as prominent. Zero of the 18 focal patients had a malignancy compared to 3 of the 9 in the prominent group (0% vs 33%, p=0.02). Of the 27 pure FEA CNBs, 6 patients ...

Endoscopic ultrasound-guided sampling of solid pancreatic masses: the fine needle aspiration or fine needle biopsy dilemma. Is the best needle yet to come?
Percutaneous needle core biopsy may be the definitive procedure where important diagnostic and prognostic information in acute and persistent renal allograft dysfunction is normally obtained. the promise of improving diagnostic precision and developing fresh, processed molecular pathways for restorative treatment will also be offered. Intro Renal biopsy remains the platinum standard by which essential diagnostic and prognostic info is definitely acquired after kidney transplantation.1,2 Biopsy methodologies have been devised to assess the acceptability of an organ before transplantation and to assess and forecast renal allograft overall performance after implantation. Renal transplant biopsy samples are analyzed from the same traditional and modern techniques as are used to assess samples from native kidneys (Package 1). With this Review, we describe the practical part D-106669 of renal biopsy in the management of renal allograft recipients and spotlight the changes that take place in renal ...

The optimum technique for biopsy assessment of the nature of a major salivary gland mass remains controversial. Fine needle aspiration cytology (FNAC) has been the traditional and popular choice, but sampling of cellular clusters is largely associated with high non-diagnostic and false-negative rates, even under optimised circumstances. Ultrasound-guided core biopsy (USCB) provides a core of tissue that allows preservation of tissue architecture and that can be histologically and immunohistochemically examined, thereby improving the chances of a meaningful diagnosis. Although relatively recently applied in the pre-operative investigation of salivary lesions, USCB shows higher levels of accuracy and reduced non-diagnostic rates when compared with FNAC, in addition to good patient tolerability. A degree of caution should, however, be exercised because of the potential for tumour seeding, and time delays inherent to histological processing are also unavoidable. Where available, USCB may be given preference
Econintersect: Needle biopsies have been a common diagnostic technique for prostate cancer and there is now data that indicates the procedure may have more than incidental risk. Based on research in a news article from Bloomberg, there is a risk of mortality from needle biopsies. A study in Toronto has found that nine of 10,000 patients died from antibiotic resistant bacteria within a month of undergoing a needle biopsy. Extrapolating that result to the more than 1 million precedures per year in the U.S., the implication is that more than 900 deaths could be occurring annually.. Follow up:. From Bloomberg:. Studies emerging during the past year have uncovered that a small, yet growing percentage of those undergoing routine needle biopsy tests are becoming critically ill and dying from bacterial infections. Infectious complications including sepsis, the condition Greenstein had, from prostate biopsies have more than doubled in less than a decade, studies from three countries show. Nine out of ...

Core needle biopsies for lymphoma diagnosis seriously affect diagnostics, treatment development and research Core needle biopsies (CNBs) are widely used in clinical diagnostic labs to aid in the diagnosis of malignant lymphomas and in latter years their use is increasing. CNBs provide a rapid method for obtaining tumour material and may be beneficial when the affected lymph nodes are located deep in the abdominal cavity or mediastinum and surgical excisional biopsies may be difficult to perform. However, according to the Swedish Haematopathology Quality and Standardization Committee, CNBs are insufficient for lymphoma diagnostic purposes and the guidelines state that material from surgical excisional biopsies are mandatory in order to obtain a robust histopathological evaluation of the lymph node architecture, cellular composition and growth pattern. Surgical excision biopsies also ensure that adequate material is available if additional molecular analyses should be required and also to ...
Biopsy-the removal of cells or tissue for microscopic examination-has a long history in medicine. The first percutaneous needle biopsy of the liver was reported in 1923, and the technique developed into an invaluable diagnostic tool in many organ systems.. The development of computed tomography (CT), ultrasound and magnetic resonance imaging (MRI), allowed physicians to use advanced imaging guidance with biopsies. Imaging-guided percutaneous needle biopsies achieve greater precision in targeting lesions, resulting in high sensitivities and low complication rates.. For the study, researchers looked for biopsy trends in Medicare claims data from 1997 through 2008 for 10 anatomical regions. Biopsy procedures increased from 1,380 per 100,000 Medicare enrollees in 1997 to 1,945 biopsies in 2008, representing a compound annual growth rate of 3 percent. In 2008, 67 percent of all biopsies were performed percutaneously, compared to 59 percent in 1997.. "We also found that the use of imaging guidance ...
Prostate needle biopsy is a test to look for prostate cancer. During the test, a thin, hollow needle is used to take small samples of tissue from the prostate. The samples are then tested in a lab.
For instance, let us consider a 55 year old non-smoking woman who presents with a 10 mm spiculated nodule located in the right upper lobe. Her past medical history includes a mastectomy for breast cancer six years previously. From table 3 the pre-test probability of malignancy is 44%. A TNAB is performed and a diagnosis of "malignancy" is obtained, which corresponds from the meta-analysis to a likelihood ratio of 72. From the nomogram of Fagan the post-test probability of malignancy reaches more than 98%. Had the pathologist responded "suspicious for malignancy" the post-test probability would have been around 92%. On the other hand, if the pathologist had diagnosed a "benign" lesion without being more specific, the post-test probability of malignancy is 5%. Finally, had the pathologist reported a finding of "hamartoma" the post-test probability of malignancy would have been less than 1%.. We restricted this analysis to studies that met methodological criteria for assessing diagnostic ...

A core needle biopsy is performed to rule out cancer in an abnormal area of breast tissue. A thin, hollow needle is used to remove a small amount of tissue from the breast. At SJRA, we perform core needle biopsies using imaging technology. The radiologist or breast imaging specialist will locate the abnormal area of the breast using mammography, MRI, or ultrasound technology. The images help guide the biopsy equipment to the suspicious area of the breast - hence, the terms MRI-guided biopsy, ultrasound-guided biopsy, and stereotactic (mammography-guided) core needle biopsy. Core biopsies are minimally invasive procedures; therefore, the risk of developing any complication is very low. After the biopsy has been completed, a small metallic marker (called a "clip") is placed at the biopsy site to mark the area for future imaging. Core biopsies can be performed at one of our comfortable Womens Centers in Voorhees and Turnersville. (Many other healthcare providers offer core needle biopsy only in ...

Patients were classified according to lung biopsy technique into coaxial group (318 lesions) and non-coaxial group (332 lesions). Exclusion criteria for biopsy were lesions ,5 mm in diameter, uncorrectable coagulopathy, positive-pressure ventilation, severe respiratory compromise, pulmonary arterial hypertension, or refusal of the procedure. Risk factors related to the occurrence of pneumothorax were classified into: (a) Technical risk factors, (b) patient-related risk factors, and (c) lesion-associated risk factors. Radiological assessments were performed by two ...
... ?. In other countries where costs are restrictive for breast biopsy tests the detection of breast cancer tends to be later and positives can be as high as 80%, but in the USA where we have an early detection policy and are very proactive about checking for cancers even if there is a slim chance of them being there, only about 20% of biopsies are cancerous.. What is Involved in a Breast Biopsy?. So now that you have you breast biopsy booked in your next concern is will it be painful and will it leave a scar? It very much depends on the type of breast biopsy that your Doctor has recommended for you. There are three main types of breast biopsy procedures.. Fine Needle Aspiration Biopsies. A fine needle aspiration biopsy is carried out as you would imagine with a very fine needle attached to a syringe which extract a small amount of tissue or fluid from the area of the breast that your Doctor has concerns about. This method is usually chosen when the lump of ...
Percutaneous liver biopsy is a procedure to take a tiny sample (biopsy) of your liver tissue. Percutaneous (say "per-kew-TAY-nee-us) means "through the skin." The procedure is also called aspiration biopsy or fine-needle aspiration. The tissue sample is looked at under a microscope. Your doctor can look for infection or other liver problems.. You may have some pain where the biopsy needle entered your skin (the puncture site). You may also have pain in your shoulder. This is called referred pain. It is caused by pain travelling along a nerve near the biopsy site. The referred pain usually lasts less than 12 hours. You may have a small amount of bleeding from the puncture site.. You will need to take it easy at home for 1 or 2 days after the procedure. You will probably be able to return to work and most of your usual activities after that.. ...
Fine needle aspiration (FNA) or core needle biopsy. Your doctor may choose this type of biopsy if you have swollen lymph nodes in your neck or armpit. For FNA, the doctor uses a very thin, hollow needle. For a core needle biopsy, the doctor uses a slightly bigger needle. The needle is used to take a small sample of tissue from the lymph node. For tumors deeper in the body, ultrasound or CT scans may be used to help the doctor guide the needle into place. A needle biopsy may not remove enough tissue for the pathologist to see cancerous cells. Or the sample may also be too small to tell the type of lymphoma. Because of this, most doctors dont use a needle biopsy to try to diagnose Hodgkin lymphoma. But there are times when a needle biopsy may be helpful. If you have been diagnosed with Hodgkin lymphoma, your doctor may use this to see if swelling in another part of your body is also lymphoma.. ...

The pre-treatment blood sample and tumor biopsies will be the control for the post-PV-10 blood samples and resected tumor samples. Tumor core needle biopsies will be collected from the designated injected and uninjected lesions one week prior to intralesional PV-10 therapy. Biopsy samples will be fixed in formalin and embedded in paraffin for immunohistochemical (IHC) staining. On day 0, the injected lesion will be treated with up to 5 mL of PV-10. Seven to 14 days after intralesional PV-10 treatment, the injected and uninjected lesions will be resected. A portion of each tumor equivalent to a core needle biopsy specimen will be fixed in formalin and embedded in paraffin for IHC staining. Immune cell infiltration will be compared between untreated baseline lesions and post-treatment lesions (injected or uninjected) by a blinded pathologist at Moffitt Cancer Center. Measurement is the ordinal level of the T-cell infiltration into tumors with three levels: 0, no brisk, and brisk ...

Results:. Although hemorrhage was rare, complicating 1.0% (95% CI, 0.9% to 1.2%) of biopsies, 17.8% (CI, 11.8% to 23.8%) of patients with hemorrhage required a blood transfusion. In contrast, the risk for any pneumothorax was 15.0% (CI, 14.0% to 16.0%), and 6.6% (CI, 6.0% to 7.2%) of all biopsies resulted in pneumothorax requiring a chest tube. Compared with patients without complications, those who experienced hemorrhage or pneumothorax requiring a chest tube had longer lengths of stay (P , 0.001) and were more likely to develop respiratory failure requiring mechanical ventilation (P = 0.020). Patients aged 60 to 69 years (as opposed to younger or older patients), smokers, and those with chronic obstructive pulmonary disease had higher risk for complications. ...
Background &Objectives: Evaluation of estrogen receptor (ER), progesterone receptor (PR), and (human epidermal growth factor receptor-2) Her-2 on core needle biopsies (CNBs) is increasingly in use to diagnosis early breast cancer, but its concordance with surgical excision (SE) is not well documented. Methods: The study included 100 formalin fixed, paraffin-embedded specimens of invasive breast carcinoma archived in Pathology Department of Cancer Institute, Tehran, Iran, from 2011 to 2014. Immunohistochemistry was applied to detect ER, PR, and Her-2. Results: The current study findings indicated a significant correlation of 90% between CNB and SE specimens for ER expression. The correlation between CNB and SE specimens was estimated as 81% and 97.3% for PR and Her-2, respectively. Discussion: CNB can be performed confidently to determine ER and Her-2. For PR, results obtained from CNB should be considered.

You will feel only a quick sting from the needle if you have a local anesthetic to numb the biopsy area. You may feel some pressure when the biopsy needle is put in. After a fine-needle aspiration biopsy, core needle biopsy, or stereotactic biopsy, the site may be tender for 2 to 3 days. You may also have some bruising, swelling, or slight bleeding. You can use an ice pack or take an over-the-counter pain medicine (not aspirin) to help relieve swelling and mild pain.. For 24 hours after the biopsy, do not do any heavy lifting or other activities that stretch or pull the muscles of your chest.. If you have general anesthesia for an open breast biopsy, you will not be awake during the biopsy. After you wake up, the area may be numb from a local anesthetic that was put in the biopsy site. You will also feel sleepy for several hours.. For 1 to 2 days after an open biopsy, you may feel tired. You may also have a mild sore throat if a tube was used to help you breathe during the biopsy. Using throat ...

The thyroid is a gland located in the neck. It is a part of the endocrine (hormone) system, and plays a major role in regulating the bodys metabolism. Sometimes, a sample of cells from the thyroid gland is needed to diagnose a condition. If a sample is needed, a fine needle biopsy can be performed. During this procedure, a skinny needle is inserted into the thyroid gland, and a sample of thyroid cells and fluid is drawn into the needle. The needle is then withdrawn and the cells are sent for examination. This test is usually performed in the office under ultrasound guidance by one of our physicians certified specifically in fine needle aspiration biopsy of the thyroid. This will allow us to diagnose thyroid disease or thyroid cancer; the results usually take about 10 days to return. We will call you personally with the results. ...

ACCURACY OF A NEW DEVICE FOR STEREOTACTIC CT-GUIDED BIOPSY OF THE CANINE BRAIN Alain Giroux, DVM Jeryl Jones, DVM, PhD, chair Department of Radiology ABSTRACT Computed tomography (CT) is an imaging technique that uses x-ray and computers to create cross-sectional images of structures. Stereotactic CT-guided biopsy is defined as the use of a stable apparatus to direct and perform tissue biopsies under CT guidance. For the brain, the principal advantage of stereotactic CT guidance over other biopsy techniques is its high accuracy in getting a sample from deep-seated lesions. The objectives of this study were to create an inexpensive CT-guided stereotactic device adaptable to different canine head sizes and to test the accuracy of the device for needle placement in deep-seated brain targets. A biopsy device was created that consists of four main components: a CT table fixation device, a head fixture, a needle fixture , and motion control system. Accuracy was tested using 16 head and neck specimens ...

Sixty-six percent of needle biopsies, 60% of laparoscopic cup samples, and 69% of punch samples were in agreement with the necropsy samples, differences that were not significantly different. The corresponding kappa coefficient were 0.59 for needle biopsies, 0.52 for cup biopsies, and 0.62 for punch biopsies. Discordant results did not differ between the liver lobes ...
Specifically, "Our study is notable for significant differences between core needle biopsies and excisional biopsy (surgery) in the expression level of 14 transcripts of which the majority are immune related. Of particular interest is the difference in CD68, a marker for tumor-associated macrophages. .In human breast tumors, infiltrating tumor-associated macrophages correlate with poor prognostic features, higher tumor grade and decreased disease free survival.. This may be, in part due to increased angiogenesis that has been shown in mouse models of mammary gland tumors and in human breast tumors where CD68 levels correlate with VEGF expression, ....

Since the introduction of the percutaneous needle biopsy technique in physiological and clinical metabolic research (8), numerous studies have investigated skeletal muscle fuel use by determining net changes in skeletal muscle substrate content from muscle samples collected before and after exercise. This approach has proven quite effective as it formed the basis on which our present insight in the role of muscle glycogen as a substrate source was obtained (9, 10, 12, 13). The same approach has also been applied to study the role of IMTG as a substrate source during exercise. After collection of muscle biopsy samples from the vastus lateralis before and after prolonged moderate-intensity exercise, most studies have applied chemical TG extraction analyses (51) on homogenized (mixed) muscle. Whereas several studies have reported a substantial net decrease in muscle TG content after prolonged exercise (13, 26, 29, 46, 48, 56, 89, 150, 165, 200), many others have failed to observe any significant ...

Because traumatic hematomas can often be seen with ultrasound, the authors hypothesized that iatrogenically induced hematomas could be used to guide the excision of nonpalpable lesions using ultrasound. Methods: Twenty patients with nonpalpable breast lesions detected by magnetic resonance imaging only were enrolled in this single-institution trial, approved by the institutional review board. A hematoma consisting of 2 to 5 mL of the patients own blood was injected into the breast to target the nonpalpable lesion. Intraoperative ultrasound of the hematoma ...
Fine-needle aspirate and cytology - To perform this procedure, a small gauge needle is inserted through the skin into the liver. A syringe is used to aspirate some cells from the liver. The cells are placed on a glass slide, stained and studied under a microscope. This is the least invasive and quickest test, but it has certain limitations. Because only a few cells are obtained, it is possible that a representative sample from the liver will not be obtained. It is also not possible to view the cells in their normal relationship to each other.. Needle biopsy - This procedure is similar to the fine-needle aspirate except a larger biopsy needle is used. Often, this test is performed during an ultrasound examination and is called anultrasound-guided needle biopsy. The needle biopsy gives a core of tissue, not just a few cells. The sample is fixed in formaldehyde and submitted to a pathologist for analysis (a technique called histopathology). General anesthesia is required, but the cat is ...
Conclusions.- Identifying factors that affect NGS success rates in cytology specimens is crucial for a better understanding of specimen adequacy requirements and for proper use of limited-volume tissue samples. In our practice, which uses direct smears as well as cell block sections, NGS success rates in core needle biopsy and fine-needle aspiration samples are comparable. The chance of successful testing is further increased by procuring concurrent fine-needle aspiration and core needle biopsy samples. The type of glass slides used for direct smears and the method of tissue extraction affect our DNA yield. Validating a DNA input for cytology samples that is lower than that recommended by the manufacturer has significantly increased our NGS success rate ...
Becky Garrison in Jacksonville FL observes: >>Just this week, our Urology Center, in reviewing its QA measures, wanted to know if its OK for them to ink the specimen by color to reduce specimen identification mixups. My first reaction was no because of concerns that unknown inks might interfere with fixation and ultimately IHC and the possibility of crush artefact introduced by non-pathology hands.<< I agree - no. I want them to handle the specimen as little as possible - the ink needs to be added after fixation. They could use colored pens to mark the outsides of the containers with a set of laboratory-prescribed colors that the lab would use to select cassette and slide frosting colors. I know that there are services that pre-ink the specimens, but Ive never actually seen it done.

The over-all aim of the present study was to compare the results of treatment with curative intent, with conservative treatment in men with prostate cancer (PCa) without distant metastases.. In a population-based cohort in Sweden, the predictive value of prostate-specific antigen (PSA) was evaluated and the relative survival of men considered plausible candidates for treatment with curative intent was investigated.. We also evaluated the association between curative treatment and cause-specific mortality, and over-all as well as relative survival in men diagnosed with PCa with a serum PSA level between 20 and 100 ng/ml.. Due to the uncertainly of transrectal ultrasound-guided biopsy in the diagnosis of PCa, we created a model for prostate imaging to increase the safety of guided Core Needle Biopsy (CNB) in men with suspect PCa, thereby improving staging. Material and methods. The cohorts in the first three studies were prospectively included in a population-based register (the National Prostate ...

Rigid bronchoscopy frequently shows necrotic tissue and cartilage. We did not remove the protruding cartilage, as we could see transmitted pulsations. Cartilage can sometimes be expectorated spontaneously.11 Histopathology confirms the diagnosis. Specimen can be collected by endoscopic biopsy, percutaneous needle biopsy, or open lung biopsy, all of which show tissue invasion with characteristic broad, aseptate hyphae with right-angle branching.4 In our case, the diagnosis was also confirmed by histopathological evidence of broad, aseptate hyphae.. Early diagnosis and antifungal therapy are the major determinants of final outcome.4,6,8 Surgery plays a role in debulking of the disease. Among antifungal agents, AmB is the treatment of choice. It is given in a dose of 1-1.5 mg/kg. Patients should be monitored for renal function and serum electrolytes, especially serum potassium.12,13 Liposomal AmB can be given in cases with compromised renal function and hypokalemia.

A biopsy is where a sample of tissue cells is taken from your breast and tested to see if its cancerous. You may also need a scan and a needle test on lymph nodes in your armpit (axilla) to see whether these are also affected.. Biopsies can be taken in different ways, and the type you have will depend on what your doctor knows about your condition. Different methods of carrying out a biopsy are discussed below.. Needle aspiration may be used to test a sample of your breast cells for cancer or drain a small fluid-filled lump (benign cyst). Your doctor will use a small needle to extract a sample of cells, without removing any tissue.. Needle biopsy is the most common type of biopsy. A sample of tissue is taken from a lump in your breast using a large needle. Youll have a local anaesthetic, which means youll be awake during the procedure, but your breast will be numb..

Category Interventional Brendan M. OShea, MD Bruno A. Policeni, MD Purpose Percutaneous biopsy of the spine is well established as an alternative to open surgical biopsy for diagnosis (1-4). Image guidance during biopsy of the cervical spine is critical for safety and diagnostic accuracy of spinal biopsy (1-3). Although CT-guided spinal biopsy (CTGSB) is well established, the majority of cases in the literature involve non-cervical levels. In a review of 410 consecutive patients undergoing CT-guided spinal biopsy, only 2% of interventions were performed on cervical lesions (1). We discuss two interesting cases at our institution where CTGB of the cervical spine during workup negated the need for open surgical biopsy or further surgical intervention. Materials & Methods A 24-year-old male smoker presented with neck stiffness and positional pain for 3 months. Initial workup included a cervical spine CT, which demonstrated a lytic lesion involving the C7 vertebral body with extension into the ...
Needle biopsy is the procedure used for detection of cancer, infection, or other thyroid problems. It is an image-guided, minimally invasive procedure performed by a radiologist with experience in needle aspiration.
An oncologist at the Cancer Control Convention in California strongly warned people about the dangers of needle biopsies. He showed a slide from a scan that was taken of a womans breast. Shed had a localized breast tumor (not yet metastasized) when the biopsy was first done. This scan, however, which was taken a while after the needle biopsy had been performed, showed cancer growing in a straight line between the tumor and the surface of her skin. It was growing right along the pathway of the needle that was pulled out of her! This meant that the needle biopsy procedure itself caused the mass to NOT be localized anymore, making the cancer suddenly more difficult to completely remove surgically via lumpectomy. There other accounts about the same thing happening to men with prostate cancer and it probably happens to people with other types of cancer as well who are subjected to needle biopsies ...

Introduction: The outcome of patients with metastatic colorectal carcinoma (mCRC) following first line therapy, especially with a K-ras mutation is poor with median survival of less than one year. The purpose of this study was to perform whole genome sequencing (WGS) to identify therapeutically actionable somatic events in mCRC patient samples, so as to select targeted treatment strategies for individual patients.. Methods: IRB approval was obtained and 3 patients have been enrolled. All had , 2 prior regimens and had known K-ras mutations (age 73, 45 and 50 years, all were male). Percutaneous needle biopsies of liver metastases were performed with whole blood collection for the extraction of constitutional DNA. WGS was performed using Illumina paired end chemistry on HiSeq2000 sequencing system, which yielded coverage of greater than 30X for both the normal and tumor samples. Somatic genomic alterations (point mutations and indels, copy number alterations, translocations and rearrangements) ...
Purpose The pretherapeutic assessment of prostate cancer is challenging and still holds the risk of over- or undertreatment. This prospective trial investigates positron emission tomography (PET) with [18F]fluoroethylcholine (FEC) combined with endorectal magnetic resonance imaging (MRI) for the assessment of primary prostate cancer. Experimental design Patients with prostate cancer based on needle biopsy findings, scheduled for radical prostatectomy, were assessed by FEC-PET and MRI in identical positioning. After prostatectomy, imaging results were compared with histological whole mount sections, and the PET/MRI lesion-based semiquantitative FEC-uptake was compared with biopsy Gleason scores and postoperative histology. Results PET/MRI showed a patient-based sensitivity of 95% (36/38; 95%CI: 82-99%). The analysis of 128 prostate lesions demonstrated a sensitivity/specificity/ppv/npv/accuracy of 67%/35%/59%/44%/54% (P=0.8295) for MRI and 85%/45%/68%/69%/68% (P=0.0021) for PET, which increased ...
Introduction: Pulmonary lesions located in close proximity to thoracic wall may be sampled either by tru-cut biopsy or by fine needle aspiration cytology (FNAC) of lung using 18-20 gauge needles under ultrasound guidance.. Aims and objectives: To assess the utility and safety of ultrasound guided transthoracic tru-cut biopsy and FNAC lung in the evaluation of peripherally located pulmonary lesions.. Methods: All patients with peripheral lung lesions who underwent tru-cut biopsy or FNAC of lung under USG guidance between January 2008 and January 2012 in a tertiary care hospital were included in the study. Patients were observed for one hour following the procedure and a chest x-ray was performed after that to look for any pneumothorax.. Results: 57 patients (39 males and 18 females) underwent the above procedure during the period of study. Mean age of patients was 51.3 years (range: 25-79 years). 42 patients underwent tru-cut biopsy of lung and 15 cases underwent FNAC of lung. Mean tumour sizes ...
MaDaLINA MARCU(1), E. RADU(2), MARIA SAJIN(1) (1) Department of Pathology, Carol Davila University of Medicine Bucharest; (2)Department of Cellular and Molecular Medicine, Carol Davila University of Medicine Bucharest ABSTRACT Prostate adenocarcinoma is frequently diagnosed on needle biopsies in early, organ-confined stages. New prognostic factors would help identifying at this stage patients at risk for unfavorable evolution, that would benefit from alternate therapy
This is a minimally invasive procedure that provides accurate results for lesions that are best seen on ultrasound images. During this procedure, the patient lies on their back or side. The breast radiologist will confirm the location of the lesion using an ultrasound probe. Local anesthesia is given into the skin and around the targeted lesion. A biopsy needle is then guided directly into the lesion under ultrasound guidance. Multiple tissue specimens are then obtained. These specimens are sent to a pathology lab to determine if the lesion is benign (not cancer) or malignant (cancer). At the completion of the procedure, a permanent biopsy marker is then inserted into the biopsy cavity for future reference.. ...
BACKGROUND: Neoplasm seeding is a serious complication after liver metastases biopsy. Reported incidences vary between 10% and 19% for colorectal cancer (CRC) and are unknown for breast cancer (BC). The aim of this retrospective study was to determine the frequency of tumor seeding after ultrasound-guided percutaneous biopsy of CRC and BC liver metastases.. MATERIAL AND METHODS: Unselected liver biopsies performed in the period of 2005-2012 at our institution were extracted from the National Pathology Registry. Medical records including imaging from patients with biopsy-verified BC and CRC liver metastases were retrospectively reviewed. The endpoint was the development of abdominal wall recurrence following liver biopsy.. RESULTS: Of total 2981 biopsies we identified 278 patients with CRC and 155 patients with BC biopsy-verified liver metastases. During the median follow-up of 25 months after biopsy (range 3-253 months), no seeding was recorded in patients with BC. Within the median follow-up of ...

For most patients, a sample of muscle tissue can be obtained by penetrating the skin with a needle, sparing the post-operative discomfort and risk associated with the more invasive open biopsy procedure. The site of the needle biopsy requires no sutures and heals with a low chance of infection. Needle biopsies are performed in the outpatient clinic or at the inpatient bedside. Patients with severe muscle atrophy need to undergo open biopsy, which is performed in our Ambulatory Care Center.. Patients experiencing the following symptoms may need a muscle biopsy:. ...
A Fine Needle Biopsy/Aspiration is used when more information is required about the significance of a lump or group of lumps within an area identified by a previous radiological examination.. A fine needle is inserted into the area to obtain tissue samples for Pathology testing. Some local anaesthetic will be injected in the skin before the needle is inserted. Following insertion, the needle will be guided into position using Ultrasound, CT or X‐rays to ensure the needle is in the correct position to obtain the tissue sample. This is repeated two or three times to ensure adequate sample is obtained for pathology testing.. ...
TY - JOUR. T1 - A fifteen years experience in the diagnosis and treatment of benign lung tumors.. AU - Lequaglie, C.. AU - Preda, F.. AU - Ongari, M.. AU - Alloisio, M.. AU - Ravasi, G.. PY - 1986/8/31. Y1 - 1986/8/31. N2 - Even the most sophisticated examinations, such as computerized tomography and percutaneous fine needle biopsy, often do not allow a certain preoperative diagnosis of benign lung cancer. The clinical history may also be deceiving: a smoker over 35 years of age need not necessarily have a primary lung cancer, but this event is frequent enough to justify a diagnostic thoracotomy. In our series, chest tomography proved to be useful and sometimes revealed unsuspected lesions. In contrast, bronchoscopy is useful only for centrally located lesions, and the same is true for bronchial washing and brushing. Finally, thoracotomy, possibly an axillary one with enucleation or possibly transegmentary resection, is the most frequent operation in benign lung tumors, because of the unfailing ...
Lumps or abnormalities in the breast are often detected by physical examination, mammography or other imaging studies. However, it is not always possible to tell from these imaging tests whether a growth is benign or cancerous.. A breast biopsy is performed to remove some cells - either surgically or through a less invasive procedure involving a hollow needle - from a suspicious area in the breast and examine them under a microscope to determine a diagnosis. Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed during the process.. Image-guided biopsy is performed when the abnormal area in the breast is too small to be felt, making it difficult to locate the lesion by feel (called palpation). In ultrasound-guided breast biopsy, ultrasound imaging is used to help guide the radiologists instrument to the site of the abnormal growth.. ...

Serial dilation can be necessary when attempting to introduce large diameter sheaths, particularly in patients that have scar tissue build-up in the common femoral artery (CFA) area. 2). Guidewires Guidewires access the vessel through the percutaneous needle. They also help steer catheters and devices through the vascular anatomy. Guidewires are manufactured in several different ways: they are either solid steel core wires or the steel core is wrapped in a thin steel coil. The core may also be encased in a polymer-type jacket. Recently, nitinol metal has been used for the inner core material. Guidewires usually have a floppy tip ...
7 (a) The radiologist performs a specimen radiograph to confirm the presence of calcifications in the cores. Calcifications that are faint or few in number may be difficult to detect in tissue sections. The numerous calcifications in this radiograph should be readily apparent in the histologic sections. (b) Large calcifications can chip out of the specimen rather than be sectioned. Only fragments of a calcification may be present, as seen in this case of DCIS. " In this case a large calcification is present next to numerous smaller difficult to see calcifications (arrows). The node can appear on mammography as an oval masscontaining calcifications. The gold forms black granular masses that resemble anthracotic pigment. Calcifications have dissolved in fixative. Prolonged time in formalin over several days can result in the disappearance of radiologic calcifications [21]. This should never happen with routine processing occurring within 1-2 days. Formalin must be properly buffered ...

Patients with lung cancer usually have a history of cigarette smoking. They may complain of persistent cough, recent weight loss, or other symptoms, but they may be totally without symptoms at an early stage. A chest X-ray or CT scan of the chest will usually demonstrate a nodule or mass in the lung. Such a finding in a smoker, in the absence of signs of infection, should prompt early referral to a thoracic surgeon. Sometimes a tissue diagnosis is obtained by bronchoscopy or transthoracic needle biopsy prior to further staging and therapy, but in many cases it is appropriate to proceed directly to surgical procedures with only radiology studies having been completed before surgery. This approach often prevents unnecessary delay in providing what we hope will be curative surgical therapy.. At Stanford, we feel strongly that it is critical to completely assess the stage or extent of spread of the cancer to other parts of the body before therapy is initiated. Chest CT scan will identify the size ...

A fine-needle aspiration (FNA) biopsy is often used to take cell samples from organs or from lumps that are below the surface of the skin. If a larger sample is needed, a core needle biopsy (CNB) will be used instead.. For core biopsies, after local anaesthetic has been given, a hollow needle is inserted through the skin and into the area being examined. X-ray, ultrasound, CT or MRI scanning will often be used to help guide the needle to exactly the right place.. When the needle is in position, it will cut out a small sample of tissue. For core biopsies, local anaesthetic is usually used to numb the area, so that you wont experience any pain or discomfort. ...

Magnetic resonance (MR) imaging may be used to guide tissue biopsy and apply markers. These specialized procedures require tools that are acceptable for use with MR systems. Many commercially available biopsy needles, markers, and devices (e.g., guidewires, stylets, marking wires, marking clips, biopsy guns, etc.) have undergone MRI evaluations with respect to safety issues and artifacts. The results indicated that many of the commercially available tools are not useful for MR-guided biopsy procedures due to the presence of excessive ferromagnetism and the associated artifacts that may limit or obscure the area of interest. Fortunately, several needles, markers, and devices have been developed using materials with low magnetic susceptibility specifically for utilization in MR-guided procedures.. Although most of the biopsy guns tested for magnetic field interactions and artifacts were found to be ferromagnetic, since these are not used in the immediate area of the target tissue, artifacts ...

Subject: Histoscreen cassettes I was wondering if anyone who uses the histoscreen (mesh) cassettes is experiencing any problems with processing of the tissue. We routinely use histoscreen cassettes for prostate needle biopsies (and other small biopsies). We often get 6 specimens from the same patient, so we will have 6 cassettes. Lately, weve been seeing one block out of the six that has not processed well. Today we had a block with two cores, and one of the cores was fine but the second core was terrible. My theory was that air bubbles were getting trapped in the cassettes and preventing the solutions from getting to the tissue. We do get air bubbles in the cassettes and they will float, so we swish the blocks in formalin when we put them in the formalin holding bucket. But we put eosin in our 95% alcohol and the cores are colored pink so I know that at least the alcohol is getting in. Also, I cant explain why one core in a block would be fine and the second core is not. I dont think this ...
3967 Backgrounds/Aims: We have developed a highly sensitive, simple assay for multiple Melanoma-Antigen Genes(MAGE) and applied it to develop sputum-based cellular diagnostics for screening of lung cancer. MAGE genes coding for a tumor antigen recognized by cytotoxic T lymphocytes, are expressed in a variety of cancer tissues, but not in normal tissues except testis. MAGE A family consists of several subtypes including MAGE A-1 to -12. After comparing gene sequences, we designed multiple MAGE recognizing primers that can bind to the cDNA sequences of MAGE-1, -2, -3, -4a, -4b, -5b, and -6 in order to increase the MAGE detection rate in RT-PCR assay. Materials and Method: Five hundred specimens of induced sputum collected after nebulization with hypertonic saline were used for MAGEA1-6 assay. Conventionally collected sputum specimens were processed by Papanicolau staining for cytologic examination. The confirmatory diagnosis was made by bronchoscopic or percutaneous needle aspiration biopsy. ...

Inflammatory myofibroblastic tumor (IMT), normally referred to as inflammatory pseudotumor, is a fairly rare condition. Fine needle aspiration cytology (FNAC) of IMT has only rarely been reported. Here, we describe one such case of pulmonary inflammatory myofibroblastic tumor. A 30-year-old man presented with a 2.8cm-sized mass in his lung. Chest CT revealed a well defined, poorly enhancing mass. FNAC showed some fascicular or swirled clusters of spindle cells, admixed with occasional inflammatory cells and foamy histiocytes. The majority of the tumor cells evidenced bland, elongated nuclei, but infrequent pleomorphic nuclei. Some of the tumor cells evidenced nuclear grooves and intranuclear inclusions. Although the cytological differentiation of IMT from malignant lesions is not immensely problematic, due to the general paucity of cytological and nuclear atypia, a definite cytological diagnosis of IMT cannot be rendered simply by FNAC. Therefore, a diagnosis of IMT may be suggested via ...
Thyroid: Surgical diseases of the thyroid gland include benign nodules, thyroid cancers, and hyperfunctioning states such as Graves disease. Thyroid nodules are commonly discovered on physical exam or when a radiologic study of the neck is performed for other reasons. Most of these nodules are benign, but about 10% can contain thyroid cancer. The initial workup of these nodules is most often performed by primary care physicians, endocrinologists, or endocrine surgeons. The evaluation will include laboratory analysis, ultrasound, and often a fine needle biopsy. Both diagnostic ultrasound and ultrasound-guided fine needle aspiration biopsy of the thyroid are performed in the office, and can usually be accomplished at the time of first consultation. If the biopsy diagnoses or raises suspicion for thyroid cancer, a thyroidectomy is usually necessary. The ultrasound also allows for a thorough evaluation of lymph nodes that may be involved with thyroid disease.. Benign thyroid diseases such as ...
Recommendation: The clinical presentation is consistent with a cold thyroid gland nodule. The possibility of malignancy is not excluded based on normal thyroid gland function. The workup of such thyroid gland nodules evolved over the past decade. Currently, an ultrasound-guided fine needle biopsy is recommended. The results of the cytology can guide the treatment: observation is recommended for a macrofollicular pattern or clear benign colloid pattern, while surgery is recommended for microfollicular pattern or clear evidence of carcinoma.. The extent of surgery is dictated by the histology as well: a hemithyroidectomy is reasonable if the needle biopsy was not diagnostic of carcinoma but showed a microfollicular pattern. In such a case, it is recommended to perform frozen section histopathology examination of the surgical specimen and proceed to total or subtotal thyroidectomy if cancer was found on the frozen section diagnosis. On the other hand, a total or subtotal thyroidectomy is ...
