Anal cytology has increasingly been used to screen for anal intraepithelial neoplasia (AIN) among men who have sex with men (MSM) at increased risk for anal cancer. Use of liquid-based cytology has been reported to reduce fecal and bacterial contamination and air-drying artifact compared with conventional cytology. Costs associated with liquid-based cytology, however, may limit its use in resource-limited settings.Anal swab samples were collected from MSM participants and used to prepare conventional and liquid-based cytology slides. Abnormal conventional cytology results triggered referral for high-resolution anoscopy and biopsy. Agreement between the 2 cytology techniques and the positive predictive value ratios of histology confirmed AIN were calculated.Among 173 MSM, abnormal anal cytology was identified in 46.2% of conventional and 32.4% of liquid-based slides. The results agreed in 62.4% of cases with a κ value of 0.49 (P | 0.001). HIV-infected MSM had a 3.6-fold increased odds of having

Imprint is a touch preparation in which the cut surface of the tissue is touched gently on a glass slide which leaves behind its impression in the form of cells. Touch imprint cytology is an important diagnostic tool in surgical oncology. It is reliable and economical providing excellent cellular details. The simplicity, speed and cost effectiveness along with the ability to maximize cell recovery even from a tiny tissue makes imprint cytology a valuable resource in diagnostic medicine. Renal tumors have distinct cytological features that facilitate diagnosis on touch imprint cytology. In the present study, correlation of imprint cytology with histopathological diagnosis was done in three cases of renal tumors. DOI: 10.21276/APALM.1268 ...

Cytodiagnosis is a very complex process, with the final conclusion being dependent on many factors, including: detailed site-specific knowledge; experience of normality; familiarity with the numerous appearances of disease; awareness of mimics and artefacts; clear understanding of the limitations of the technique; and detailed clinical information. 1 Morphology Specimen cellularity provides us with important information about the target organ/tissue. The number and type of cells present give important information about the target tissue. Consequently this represents a prime opportunity to engage in early innovative research in this field. 6 VIRTUAL MICROSCOPY IN EDUCATION 23 we can take these images into the diagnostic arena through the development of automated devices for quantitative assessment. A major consideration in implementing such systems will be the computational challenge in processing these images. The current PC/software framework will simply not provide enough computational power, ...

Cytologic examination of the mediastinal lymph nodes was also performed by EBUS-guided aspiration and it was prepared using liquid-based cytology (Thin Prep, Cytyc Corporation, Boxborough, MA, USA) by Papanicolaou stain. The cellularity was relatively low and tumor cells were individually scattered with a few small loosely cohesive clusters on a clean background. A few tumor cells were arranged in vague microacini, linear cords or tight small clusters (Fig. 1F). The nuclear features ranged from a bland nucleus with round borders and fine chromatin to a pleomorphic nucleus with irregular borders and clumped chromatin. The nucleoli were often seen in multiples and appeared small, but distinct. Tumor cells occasionally exhibited binucleation or multinucleation (Fig. 3A) and few Reed-Sternberg cell-like cells with markedly irregular nuclei and prominent nucleoli were identified (Fig. 3B). None of the tumor cells, even pleomorphic cells, exhibited nuclear hyperchromasia. There were no mitotic ...

Introduction: Non-human primates (NHP) are frequently used in preclinical research, including xenotransplantation studies. Cytological examination of bone marrow (BM) is a helpful adjunct for a complete interpretation of hematological data. In this light, the aim of this work is to evaluate the cellular composition of BM in immunosuppressed xenotransplanted NHP. Materials and Methods: Ten NHP recipients of a life-supporting porcine kidney were treated with Cyclosporin A, steroids, Mycophenolate sodium, with Cyclophosphamide (CYP) (N=6) or Rituximab (N=4). Eight animals were euthanized for kidney failure and 2 for life-threatening conditions. A complete pre-euthanasia CBC and 4 femoral BM smears collected at euthanasia were performed. Cytological evaluations and differential counts of erythroid, granulocytic, lymphocytic and plasmacytic series were performed. Megakariocytic series elements were evaluated with regards to number, morphology and maturation. The myeloid to erythroid ratio (M:E) was ...

Sampling techniques are combined during bronchoscopy to increase the diagnostic yield for endobronchial malignant tumours. Bronchial biopsy provides the definitive histological diagnosis in most cases, but accompanying cytological procedures such as washing, brushing, needle aspiration or imprint cytology can increase diagnostic yield. In this prospective study, a different cytological technique, that could enhance the diagnostic yield of bronchoscopy without increasing its time or cost, was tested. Flexible bronchoscopy was performed in 93 patients suspected of having pulmonary neoplasms. Bronchial biopsies were initially placed in a balanced salt solution. When bronchoscopy was finished, all visible tissue fragments were removed and placed in formalin to undergo histopathological examination and the rinse fluid was sent for cytological examination. Washing was performed routinely but no cytological brushing was employed. Eighty-two patients had final diagnoses of malignant neoplasm. In four ...

Frankly invasive carcinoma is usually diagnosed in women with symptoms suggesting cancer but cytology may sometimes be taken as part of the investigation. Cytology is regarded as unreliable in clinical cancer because associated haemorrhage and inflammation tends to obscure the nuclear detail. A recent study from the NHS Cervical Screening Programme has shown that cytology in symptomatic young women (20-29 years) with cancer may be more reliable than formerly thought (Landy et al. 2015). It should be noted that the majority of cancers at that age are likely to be early cancers (stage IA or IB) rather than advanced clinical cancers. Microinvasive (stage IA) squamous cell carcinoma almost always develops in a background of extensive CIN3, which is the abnormality likely to be seen in cytology samples. Women with stage IA are likely to be asymptomatic and their cancers screen-detected by cytology.. Women with early invasive cancer (IB1) may also be asymptomatic and detected on cytology. Occult ...

Immediate fixation of LBC samples improves preservation of cellular morphology and reduces air-drying and crush artefacts compared with CP. Cellular components such as cell membranes and chromatin may appear more sharply defined in LBC preparations than in CP as a result of improved cell preservation. Cell sizes appear slightly smaller in LBC preparations than in CP, however overall cellular morphology is unchanged. Tissue architecture in larger cell groups may be better appreciated in CP compared with LBC, however small cellular clusters and tissue fragments are still preserved.. ...

Mutual competition of nearby organizing regions. The induction of new organizing regions by implantation of tissue fragments derived from the endogenous organizing region has been investigated in the chick [1] (Khaner and Eyal-Giladi, 1989) and extensively in hydra [2,3]. In general, implantation of such tissue at a distance from an existing organizer can be successful, while a more proximal implantation may not. Removal of the endogenous organizing region greatly enhances the probability to form a new organizing region. This behavior is a straightforward consequence of the general pattern forming mechanism proposed, as demonstrated by the following simulations: ...

The examination of brush cytology specimens has become an established diagnostic technique in the investigation of patients with suspected pancreatic, bile duct, gallbladder, and ampullary tumours. We have reviewed 448 consecutive brush samples obtained from 406 patients and correlated the findings with pathological and clinical outcomes. To our knowledge, this is the largest series of pancreatico-biliary brush cytology specimens yet reported.. As with previous studies, we found that the brush cytology technique produced cellular samples of good quality in most instances. Only 26 of 489 (5.3%) specimens were considered inadequate for diagnosis. Seven patients with initial unsatisfactory cytology samples underwent repeat endoscopy and an adequate specimen was obtained in six cases. The number of unsatisfactory specimens has not been specifically noted in many previous studies although rates of 0-6% were documented in three series.9, 11, 18 There was no clear correlation between unsatisfactory ...

N2 - BACKGROUND. The advent of cDNA microarrays and other molecular technologies necessitates the acquisition of tumor cell-enriched material because nonmalignant cells often decrease the sensitivity of the assays. Fine-needle aspiration (FNA) specimens from carcinoma have long been noted to be enriched in malignant cells. The current study quantitated the relative representation of tumor versus nontumor cells in FNA specimens compared with tissue sections using breast carcinoma as a model. METHODS. Five patients who had undergone both a diagnostic FNA and a surgical excision for breast carcinoma between January and July of 1996 were selected. Five random cellular fields from representative slides of the FNA (using the ThinPrep preparation of the wash) and surgical excision specimens were photographed ...

Cleveland, Ohio. Diagnoses of specific nongynecologic cytology samples may be enhanced with knowledge of certain laboratory test results. These include both exfoliative samples (cerebrospinal fluid, pericardial, peritoneal and pleural fluids) as well as fine needle aspirate cytology samples from body sites such as the thyroid, neck, lymph nodes and metastatic sites. Following an overview of the subject, a case-based approach is used to highlight laboratory tests that aid in rendering more specific cytologic diagnoses. The use of immunocytochemical stains on cytologic samples to help make more specific diagnoses are also covered.. ...

BACKGROUND Molecular testing of lung adenocarcinomas (ADCs) is crucial for therapy stratification of patients. Because of the often limited diagnostic material, the authors aimed to explore the suitability of cytology smears for next-generation sequencing (NGS) and compared the results with concurrent histological specimens or cell blocks. METHODS A total of 16 formalin-fixed paraffin-embedded (FFPE) ADCs with known genetic alterations were used as the first cohort for targeted DNA and RNA sequencing. In the second cohort of 8 cases, 8 cytological smears were compared with matching histological specimens or cell blocks for the study. For NGS library amplification, commercially available panels for DNA and RNA sequencing were applied. The Ion Torrent Personal Genome Machine and the Ion Reporter workflow (version 5.0) were used for sequencing. RESULTS All DNA libraries derived from FFPE and non-formalin-fixed cytological smear samples produced acceptable quality metrics, thereby enabling ...

Discussion. The FNA smears were moderately cellular and composed of a predominant population of spindle cells arranged in large tissue fragments, loose cohesive groups, and as isolated cells (Figure 1). The tumor cells had varying amounts of delicate and pale cytoplasm and indistinct cell membranes. The nuclei appeared elongated and cigar-shaped with blunted-end (Figure 2). There was mild to moderate nuclear atypia in terms of anisonucleosis and prominent nucleoli (Figure 3). A preliminary cytological diagnosis of spindle cell tumor was made. Immunoperoxidase stains were subsequently performed on the cellblock. The tumor cells exhibited strong c-kit (Figure 4) and vimentin immunoreactivity but negative for S-100 protein, smooth muscle actin (SMA) and cytokeratin. A final cytologic diagnosis of GIST was, therefore, made based on cytological and immunocytochemical findings.. Cytologic Diagnosis: Gastrointestinal Stromal Tumor (GIST). Histologic Features.

Despite progress in recent years towards the early detection of gastric cancer in the western country and Japan, most patients will already have advanced disease at diagnosis in our country. The majority of patients will die of recurrent disease, even if surgery is thought to be curative at the time.. Recent advances in preoperative diagnosis using ultrasonography or computed tomography provide much more information on peritoneal metastasis before operation. However, it is impossible to obtain information about small peritoneal metastasis preoperatively. Therefore, PWC must be performed in addition to macroscopic observation and palpation in patients with advanced gastric cancer. Therefore, cases positive for PWC are considered as peritoneal metastasis, according to the JCGC [10,11].. The prognostic value of positive cytology findings was recently confirmed also in the West, and a new stage classification for gastric carcinoma, recently published by Japanese Gastric Cancer Association, employs ...

Anatomical pathology is the study of organs and tissues to determine the causes and effects of particular diseases. An anatomical pathologists findings are fundamental to medical diagnosis, patient management and research. Anatomical pathology involves macroscopic pathology, histopathology (the combination of these two usually being referred to as surgical pathology), cytopathology and morbid anatomy. Histopathology is concerned with the microscopic examination of tissues, taken either as biopsy samples or resection specimens. Tissues are assessed macroscopically, and material is taken for microscopic examination for the purpose of diagnosis, prognosis and directing appropriate treatment. Cytopathology is the study of individual cells aspirated or obtained from body fluids or tissues, including exfoliative cytology, to detect abnormalities. Morbid anatomy is the use of the autopsy to determine cause of death and investigate both the associated and incidental (unrelated to cause of death) ...
