Anaplasia: Loss of structural differentiation and useful function of neoplastic cells.Wilms Tumor: A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.Rhabdomyosarcoma, Embryonal: A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy.

Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs.

The tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. Histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. Medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis.

Loss of p53 promotes anaplasia and local invasion in ret/PTC1-induced thyroid carcinomas. (1/38)

Papillary thyroid carcinomas in humans are associated with the ret/PTC oncogene and, following loss of p53 function, may progress to anaplastic carcinomas. Mice with thyroid-targeted expression of ret/PTC1 developed papillary thyroid carcinomas that were minimally invasive and did not metastasize. These mice were crossed with p53-/- mice to investigate whether loss of p53 would promote anaplasia and metastasis of ret/PTC1-induced thyroid tumors. The majority of p53-/- mice died or were euthanized by 17 weeks of age due to the development of thymic lymphomas, soft tissue sarcomas, and testicular teratomas. All ret/PTC1 mice developed thyroid carcinomas, but tumors in p53-/- mice were more anaplastic, larger in diameter, more invasive, and had a higher mitotic index than tumors in p53+/+ and p53+/- mice. Thyroid tumors did not metastasize in any of the experimental p53+/+ and p53+/- mice +info)

Association of expression of CD44v6 with systemic anaplastic large cell lymphoma: comparison with primary cutaneous anaplastic large cell lymphoma. (2/38)

CD44 is a ubiquitous multifunctional cell surface adhesion molecule family. High expression of the standard form, CD44s (CD44), and its variant form, CD44v6, has been reported to be associated with tumor dissemination in non-Hodgkin lymphoma. To evaluate the potential role of CD44 and/or CD44v6 in different entities of anaplastic large cell lymphoma (ALCL), 30 cases of systemic ALCL (sALCL; 20 cases) and primary cutaneous ALCL (cALCL; 10 cases) were compared for expression of CD44 and CD44v6 by immunohistochemical staining. Expression of CD44v6 also was analyzed with respect to expression of anaplastic lymphoma kinase (ALK) in sALCL. No difference of CD44 expression was noted between sALCL and cALCL In contrast, expression of CD44v6 was found in 18 (90%) of sALCL cases and in 5 (50%) of cALCL cases. There was no correlation between expression of CD44v6 and expression of ALK in sALCL. These results indicate that expression of CD44v6 rather than CD44 correlates with sALCL. Furthermore, these results suggest that CD44v6 and ALK may be independent predictors of risk for the systemic phenotype of ALCL.  (+info)

Clinical and biologic significance of nuclear unrest in Wilms tumor. (4/38)

BACKGROUND: Nuclear unrest is a term applied to Wilms tumors (WT) with favorable histology that show nuclear enlargement similar to that seen in anaplasia but with no abnormal mitotic figures. This study was undertaken to evaluate the clinical and pathogenetic significance of WT with nuclear unrest. METHODS: The authors reviewed primary nephrectomy specimens and clinical data from 173 patients who were treated for WT on 1 of 5 consecutive clinical trials at St. Jude Children's Research Hospital. A subset of 70 patients was selected for p53 immunohistochemistry. Seventeen samples of recurrent tumors were also reviewed. RESULTS: WT with nuclear unrest had age and stage distribution similar to that for WT with favorable histology. Patients who had tumors with favorable histology, nuclear unrest, and anaplastic histology had 5-year cumulative incidences of recurrence of 12.2%, 22.2%, and 36.4%, respectively (P = 0.010). Despite the difference in recurrence incidence, patients who had tumors with nuclear unrest and patients who had tumors with favorable histology had nearly identical overall survival. Immunostaining for p53 was positive in 2 of 24 tumors (8.3%) with favorable histology, 1 of 25 tumors (4%) with nuclear unrest, and 16 of 21 tumors (76%) with anaplastic histology (P < 0.001). Histologic review of samples from recurrent tumors showed that 7 of 10 of primary tumors converted from favorable histology to either nuclear unrest or anaplastic histology in the recurrent tumor. CONCLUSIONS: WT with nuclear unrest more closely resembles favorable histology than anaplastic histology, both clinically and pathogenetically. Analysis of samples from recurrent tumors suggests that WT with nuclear unrest represents an intermediary in the continuum from favorable histology to anaplastic histology. For treatment stratification, it is appropriate to continue grouping nuclear unrest with favorable histology, although a larger analysis will be necessary to confirm the current findings.  (+info)

Gangliogliomas: A report of five cases. (5/38)

Gangliogliomas are rare tumors of the Central Nervous System. Five gangliogliomas were diagnosed out of 1560 brain tumours surgically resected out in a period of 5 years accounting for 0. 32%. We have tried to discuss in detail the pathological features of these tumours and have mentioned the clinical and radiological features associated with them. All the slides, tissue blocks and pathology reports of the surgical specimens of gangliglioma were reviewed and the clinical and radiological data reviewed. The ages of the patients ranged from 7-65 years with 4 males and 1 female. The tumors were located in the lateral ventricle (a rare site), temporal, parietal and the frontal lobes with duration of seizures varying from 1-9 years. The tumors were diagnosed by the presence of a dual population of neoplastic ganglionic and glial components. The glial components consisted of pilocytic astrocytes (l case), fibrillary astrocytes (2 cases), oligodendrocytes (1 case) and anaplastic astrocytes and oligodendrocytes (1 case). There was one-grade I GG, three-Grade II GGs and one-grade III GG. Astrocytes were the commonest glial component of GGs, either pilocytic or fibrillary. Oligodendrocytes as the glial component of GGs was seen in 2 cases one of which was anaplastic and this is a rare finding.  (+info)

Increased p53 immunopositivity in anaplastic medulloblastoma and supratentorial PNET is not caused by JC virus. (6/38)

BACKGROUND: p53 mutations are relatively uncommon in medulloblastoma, but abnormalities in this cell cycle pathway have been associated with anaplasia and worse clinical outcomes. We correlated p53 protein expression with pathological subtype and clinical outcome in 75 embryonal brain tumors. The presence of JC virus, which results in p53 protein accumulation, was also examined. METHODS: p53 protein levels were evaluated semi-quantitatively in 64 medulloblastomas, 3 atypical teratoid rhabdoid tumors (ATRT), and 8 supratentorial primitive neuroectodermal tumors (sPNET) using immunohistochemistry. JC viral sequences were analyzed in DNA extracted from 33 frozen medulloblastoma and PNET samples using quantitative polymerase chain reaction. RESULTS: p53 expression was detected in 18% of non-anaplastic medulloblastomas, 45% of anaplastic medulloblastomas, 67% of ATRT, and 88% of sPNET. The increased p53 immunoreactivity in anaplastic medulloblastoma, ATRT, and sPNET was statistically significant. Log rank analysis of clinical outcome revealed significantly shorter survival in patients with p53 immunopositive embryonal tumors. No JC virus was identified in the embryonal brain tumor samples, while an endogenous human retrovirus (ERV-3) was readily detected. CONCLUSION: Immunoreactivity for p53 protein is more common in anaplastic medulloblastomas, ATRT and sPNET than in non-anaplastic tumors, and is associated with worse clinical outcomes. However, JC virus infection is not responsible for increased levels of p53 protein.  (+info)

Multiple metastases to the small bowel from large cell bronchial carcinomas. (7/38)

AIM: Metastases from lung cancer to gastrointestinal tract are not rare at postmortem studies but the development of clinically significant symptoms from the gastrointestinal metastases is very unusual. METHODS: Formalin-fixed, paraffin-embedded tissues were cut into 5 microm thick sections and routinely stained with hematoxylin and eosin. Some slides were also stained with Alcian-PAS. Antibodies used were primary antibodies to pancytokeratin, cytokeratin 7, cytokeratin 20, epithelial membrane antigen, vimentin, smooth muscle actin and CD-117. RESULTS: We observed three patients who presented with multiple metastases from large cell bronchial carcinoma to small intestine. Two of them had abdominal symptoms (sudden onset of abdominal pain, constipation and vomiting) and in one case the tumor was incidentally found during autopsy. Microscopically, all tumors showed a same histological pattern and consisted almost exclusively of strands and sheets of poorly cohesive, polymorphic giant cells with scanty, delicate stromas. Few smaller polygonal anaplastic cells dispersed between polymorphic giant cells, were also observed. Immunohistochemistry showed positive staining of the tumor cells with cytokeratin and vimentin. Microscopically and immunohistochemically all metastases had a similar pattern to primary anaplastic carcinoma of the small intestine. CONCLUSION: In patients with small intestine tumors showing anaplastic features, especially with multiple tumors, metastases from large cell bronchial carcinoma should be first excluded, because it seems that they are more common than expected.  (+info)

Salvage chemotherapy with cyclophosphamide for recurrent temozolomide-refractory anaplastic astrocytoma. (8/38)

BACKGROUND: A prospective Phase II study of cyclophosphamide (CYC) was conducted in adult patients with recurrent temozolomide-refractory anaplastic astrocytoma (AA) with a primary objective of evaluating 6-month progression-free survival (PFS). METHODS: Forty patients (28 men, 12 women) ages 26-57 years (median, 43 yrs) with neuroradiographically recurrent AA were treated. All patients had previously been treated with surgery and involved-field radiotherapy. Additionally, all patients were treated with temozolomide (TMZ) chemotherapy after radiotherapy. All patients were treated at recurrence with CYC administered intravenously on 2 consecutive days (750 mg/m2/day) every 4 weeks (operationally defined as a single cycle). Neurologic and neuroradiographic evaluation were performed every 8 weeks. RESULTS: All patients were evaluable. A total of 215 cycles of CYC (median, 4 cycles; range 2-12 cycles) was administered. CYC-related toxicity included alopecia (all patients, 100%), anemia (5, 12.5%), thrombocytopenia (6, 15%), and neutropenia (8, 20%). Four (10%) patients required transfusion. Nine patients (22.5%) (95% confidence interval [95% CI], 11%-39%) demonstrated a neuroradiographic partial response, 16 patients (40.0%) (95% CI, 25%-57%) demonstrated stable disease, and 15 patients (37.5%) (95% CI, 23%-54%) had progressive disease after 2 cycles of CYC. Time to tumor progression ranged from 2-19 months (median, 4 mos; 95% CI, 2-6 mos). Survival ranged from 2-26 months (median, 8 mos; 95% CI, 6-10 mos). The 6-month and 12-month PFS was 30% and 8%, respectively. CONCLUSIONS: CYC demonstrated modest efficacy with acceptable toxicity in this cohort of adult patients with recurrent anaplastic astrocytoma, all of whom had failed prior TMZ chemotherapy.  (+info)

The identification of EGFR overexpression in a significant proportion of anaplastic Wilms tumors and mesoblastic nephromas highlights the potential for targeted therapy in a histologically defined subset of children with renal malignancies. In particular, there was a striking association with CCSK, the second most common renal tumor in children following Wilms tumor, which has a significantly reduced survival (15), and for which the molecular genetics underlying the disease are largely unknown. We have observed an up-regulation of the EGFR pathway in all cases of CCSK examined, as suggested by a recent expression profiling study (10). This involved a combination of overexpression, gene amplification, p-Akt up-regulation, and mutations in both EGFR and PTEN.. Of particular interest is the discovery of a somatic T790M mutation in EGFR in an untreated case of CCSK. Despite the initial success of compounds targeting the receptor in patients with activating EGFR mutations, resistance seems to ...
Renal anaplastic sarcoma is a rare tumour of the kidney. By 2017 about 25 cases have been reported. This tumour occurs in children and young adults and is more common in females than males. Because of its rarity its natural history is not well understood. The age at diagnosis of this condition varies between 10 months to 41 years. The male:female ratio is 2:3. The most common presentation is an asymptomatic abdominal mass. The tumour is more common on the right and it may metastise to lung, liver and bone. Aspiration cytology may be of use in making the diagnosis. CT scans of the abdomen and the rest of the body are normally done to assist in surgical planning. On histology the tumours have a marked spindle cell component. Other cells may be bizarre in shape. Cartilage or bone tissue may be found. A cystic component may be present.

Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods: We included 61 cases diagnosed as CHL, ALCL, and anaplastic variant of DLBCL. We reviewed morphologic microscopic findings by conventional staining and immunohistochemistry (IHC) with antibodies against PAX-5, CD30, CD15, CD45, EMA, ALK-1, and LMP-1. Results: Fifty cases corresponded to CHL (81.97%), 4 cases to ALCL (6.56%), and 4 cases to DLBCL (6.56%) excluding 3 cases, which remained unclassifiable (4.92%). PAX-5 was expressed in 94% of CHL and 100% of DLBCL cases. LMP-1 was expressed in 52% of CHL and 25% of DLBCL cases. EMA was invariably expressed in all 4 cases of ALK+ALCL. It was expressed in 4/50 cases (8%) of CHL and in

Liver: 90 - 95% of the tissue is replaced by a poorly demarcated, non encapsulated, infiltrative, multilobulated and densely cellular mass with small groups of remaining hepatocytes. Neoplastic cells are closely packed, supported by scant amount of fibrovascular stroma and arranged in anastomosing cords, islands and sheets. The neoplastic cells are polygonal to spindleoid, 15 to 30 μm in size with indistinct cell borders and have a high amount of granular eosinophilic cytoplasm and often contain birefringent olive-green to golden-brown granular pigment within the cytoplasm. Nuclei are round to oval to irregular with finely stippled chromatin and have up to three prominent nucleoli. Many cells contain up to five oval to irregular nuclei or have a huge nucleus (megakaryosis). Anisocytosis and anisokaryosis are high and there is anaplasia of neoplastic cells. In 10 HPF there are nine mitotic figures, some of which are bizarre. There are multifocal randomly distributed areas of necrosis, ...

Cell-free DNA (cfDNA) and circulating tumor cells (CTCs) are promising prognostic and predictive biomarkers in non-small cell lung cancer (NSCLC). In this study, we examined the prognostic role of cfDNA and CTCs, in separate and joint analyses, in NSCLC patients receiving first line chemotherapy. Seventy-three patients with advanced NSCLC were enrolled in this study. CfDNA and CTC were analyzed at baseline and after two cycles of chemotherapy. Plasma cfDNA quantification was performed by quantitative PCR (qPCR) whereas CTCs were isolated by the ScreenCell Cyto (ScreenCell, Paris, France) device and enumerated according to malignant features. Patients with baseline cfDNA higher than the median value (96.3 hTERT copy number) had a significantly worse overall survival (OS) and double the risk of death (hazard ratio (HR): 2.14; 95% confidence limits (CL) = 1.24-3.68; p-value = 0.006). Conversely, an inverse relationship between CTC median baseline number (6 CTC/3 mL of blood) and OS was observed. In

The genetics of Wilms tumor (WT), a pediatric malignancy of the kidney, is complex. This disease is named after Dr. Max Wilms, a German surgeon (1867-1918) who firstly described this disease [1,2]. WT is a malignant tumor containing metanephric blastema, epithelial derivatives and stromal. Characteristic of this tumor is the presence of glomeruli and abortive tubules surrounded by a spindle cell stroma . The stroma consists of striated muscle, cartilage, bone, adipose tissue, fibrous tissue composition [1-3]. Clinically, the tumor compresses the kidney parenchyma, inhibiting normal function. In most children, the causes of WT are unknown. Very rarely, children that develop WT have other specific conditions present at birth, mainly congenital malformations. Moreover, mutations in WT1 on chromosome 11p13 are observed in about 20% of WTs [4]. At least 50% of the wilm tumor patients with WT1 mutations also carry mutations in CTNNB1, which encoding a proto-oncogene beta-catenin [5-7]. Although until ...
Imaging studies - including radiographs ("x-rays"), computerized tomography (CT), and magnetic resonance imaging (MRI) - are often used to make a presumptive diagnosis of chondrosarcoma. However, a definitive diagnosis depends on the identification of malignant cancer cells producing cartilage in a biopsy specimen that has been examined by a pathologist. In a few cases, usually of highly anaplastic tumors, immunohistochemistry (IHC)is required.. There are no blood tests currently available to enable an oncologist to render a diagnosis of chondrosarcoma. The most characteristic imaging findings are usually obtained with CT.. Nearly all chondrosarcoma patients appear to be in good health. Often, patients are not aware of the growing tumor until there is a noticeable lump or pain. Earlier diagnosis is generally accidental, when a patient undergoes testing for another problem and physicians discover the cancer. Occasionally the first symptom will be a broken bone at the cancerous site. Any broken ...
The goal of this work was to demonstrate prospectively that maximal surgical resection of low grade oligodendrogliomas without adjuvant therapy does not reduce life expectancy over that of historical controls. All patients with surgically accessible grade II oligodendrogliomas underwent maximal resection using stereotactic guidance and/or cortical mapping and were followed with serial MRI scans without adjuvant therapy until either progression or spread into brain regions deemed not surgically resectable. Nineteen patients were treated between 1993 and 2006. Ten patients required reoperation an average of 55 months after their first surgery. Nine patients progressed to anaplastic tumors an average of 42 months after their first surgery: six patients died from their tumors an average of 73 months after diagnosis, two are still alive 76 and 18 months after progression, and one was lost to follow up. Ten patients are alive and progression-free an average of 116 months after diagnosis, one of whom was lost
To reach these conclusions, Jewett and Eversole first characterized the 300 specimens (from autopsy, cystectomy and transurethral resections) using Jewetts staging system: A, submucosa only; B1, less than halfway through the muscle; B2, halfway or more through the muscle; C, perivesical fat or prostate. They immediately found that the majority of cases of lymphatic invasion were stage B2 or C. In addition, well-differentiated tumors (low-grade) remained low-stage; and poorly differentiated, squamous and anaplastic tumor types were much more likely to reach the lymphatics at earlier-stages ...

The papillomas induced in domestic rabbits with virus procured from cottontails undergo progressive changes in the direction of malignancy when they grow vigorously. From the beginning they exhibit the traits whereby tumors are characterized, and they have malignant potentialities. In seven animals of a group of ten carrying papillomas for more than 200 days, cancer has developed, and in an eighth a tumor of problematic malignancy has arisen. One of the remaining two rabbits died early in the cancer period, and the papillomas of the other eventually retrogressed. Ten cottontails with induced growths of much longer duration have not developed cancer.. The malignant tumors have all been acanthomatous in type, and have arisen directly from the papillomas by graded, continuous alterations. These have often gone further after malignancy has been attained, and have eventuated in great anaplasia. Metastasis has been frequent, and transplantation to another host has proved successful. Individual growths ...
The Mr 52,000 cathepsin D is the precursor of a lysosomal protease secreted in excess by breast cancer cells. This protease can degrade extracellular matrices and proteoglycans and is induced by estrogens in estrogen receptor-positive breast cancer cell lines. In a 4- to 6-yr retrospective cohort study, the concentration of the total cathepsin D (precursor plus intermediate and mature chains) was assayed in cytosols of primary tumors from 242 pre/perimenopausal and 154 postmenopausal breast cancer patients in a solid-phase immunoassay using two specific monoclonal antibodies.. Patients were initially divided into groups with low, intermediate, or high concentrations of cathepsin D corresponding to the quartiles of the overall distribution. Using these groupings, the level of Mr 52,000 cathepsin D was not significantly associated with the recognized prognostic factors of age, lymph node involvement, tumor size, and/or grade of anaplasia. A significant association was found between cathepsin D ...

The frequency of BBC was 1,65%. One hundred and one patients had synchronous one. The mean age was 51 years. Fifty-eight percent were postmenopausal. Eleven percent had a positive family history for breast carcinoma. Mammography showed opacity with malignant features in the contralateral breast in 55,4% of the cases. The average tumor size was 46 mm. T4 stage was found in 44,8% patients. Twenty-five (24,7%) had metastatic disease at diagnosis. Bilateral surgery was performed in 72,2% whose radical one was done in 36,6% of the cases. On pathology, ductal invasive carcinoma was found in 81,1% of cases whereas lobular invasive carcinoma in 10,9%. The mean diameter of resected tumours measured by pathologists was 31,3 mm. Positive lymph nodes accounted for 61% of all tumors. Hormone receptor status was positive in 78% of the cases. Human epidermal growth factor receptor (HER2), was amplified in 23 of 69 tumors. Radiotherapy was delivered in 77,3% of patients, chemotherapy in 87% and hormonal ...

Aim: To determine whether juvenile pilocytic astrocytomas WHO grade I have the potential for spontaneous malignant transformation. Methods: A literature search was performed cross-referencing juvenile pilocytic astrocytoma, pilocytic astrocytoma, astrocytoma grade I, optic glioma, glioma, low-grade gliomas and malignant transformation, anaplasia or anaplastic change. Bibliographic PubMed and Google searches were performed, and reference ophthalmology and neuropathology textbooks were utilised. Results: A total of 49 purported cases of malignant transformation were found. Twenty of these tumours, however, did not initially match criteria for juvenile pilocytic astrocytoma WHO grade I and were excluded. Six other cases were located within the irradiated field but represented anaplasias developing independently of the primary tumour. The remaining 24 malignancies had all been previously irradiated. Conclusion: Juvenile pilocytic astrocytomas WHO grade I do not undergo spontaneous anaplastic ...
Meningiomas are mostly benign tumours that originate from the coverings of brain and spinal cord. Only a minority of cases show progression to an anaplastic tumour (WHO grades II and III). Multiple and familial cases are rare and mostly associated with (hereditary) neurofibromatosis 2 (NF2). Meningiomas show an unexpectedly high recurrence rate. Also, completely removed low-grade tumours can recur. On a cytogenetic level, meningiomas are the best-studied tumours in humans. The majority of high-grade but only a minority of low-grade meningiomas show loss of merlin, a cytoskeleton-cytoplasm-linker protein. Merlin is the product of the NF2 gene located on chromosome 22. A second tumour suppressor gene on chromosome 22 on 22q12.3 is the gene for the tissue inhibitor of metalloproteinase 3 (TIMP3), which appears to be involved in meningioma progression and a high-grade meningioma phenotype. In contrast to other solid tumours, progression of meningiomas is correlated with increasing hypodiploidy, ...

Gain of 1q is associated with adverse outcome in favorable histology Wilms tumors. Feb 158 (2): Although several genes/genetic loci involved in the etiolgy of wilms tumor have been identified, little is known of the molecular changes associated with relapse. We therfore undertook an analysis by comparative genomic hybridization (CGH) of 58 tumor samples of favorable histology Wilms tumor taken at inital diagnosis and/or relapse. The results suggest that 1q gain at diagnosis could be used to identify patients with favorable histology Wilms tumor at increased risk of relapse who might benefit from early treatment intensification.. ...
CEBPD (C/EBP delta) is a member of the CCAAT-enhancer binding protein (C/EBP) family of transcription factors characterized by a b-Zip domain that mediates dimerization and DNA binding. CEBPD is induced in response to acute stressors such as cytokine stimulation, bacterial lipopolysaccharide (LPS), corticosteroids, radiation and hypoxia. We have previously reported that CEBPD has dual functions in breast cancer by both attenuating or enhancing oncogenic pathways depending on context (Balamurugan and Sterneck, 2013, Mendoza-Villanueva et al., 2016). Recent studies reveal that elevated Endoplasmic Reticulum (ER) stress is associated with the pathology of several diseases including cancer. Limiting supply of nutrients and oxygen in growing tumor cells disrupts the protein folding homeostasis resulting in activation of the unfolded protein response (UPR). The UPR includes pathways that support adaptation to stress, and that are also implicated in promoting malignant features and therapy resistance ...

Your veterinarian will perform a thorough physical exam on your cat, including a complete blood profile, chemical blood profile, a complete blood count, a urinalysis and an electrolyte panel. A microscopic study of fluid taken from the liver by needle will be done to detect dysplasia (a pre-cancerous change in cells and tissues) and overt malignant features of cancerous cell spread. Occasionally, the only finding of the study is necrotic (dead) cells in the liver. A hepatic biopsy will need to be conducted in order to make a conclusive diagnosis. This will require that your veterinarian surgically remove a sample of liver tissue for laboratory analysis. A needle biopsy is not recommended.. ...
Brainstem glioma is impossible to resect completely, and patients with this type of glioma show a poor prognosis. Therefore, a more effective adjuvant therapy is required to prolong survival. Bevacizumab is an endothelial growth factor monoclonal antibody with strong anti-vascular effects, which may suppress tumor progression. We performed a retrospective study of data from 6 patients with brainstem glioma showing malignant features who were treated with bevacizumab. Tumor-associated lesions, as evaluated by T2 weighted or fluid-attenuated inversion-recovery magnetic resonance imaging, were reduced in all patients, although the timing of the start of bevacizumab administration and pretreatment were not uniform ...

Desmoplastic infantile gangliogliomas are a form of desmoplastic infantile tumours, and despite their aggressive appearances tend to have a good prognosis. Epidemiology The vast majority occur in children with less than one year of age, and males are more commonly affected with a M:F ratio of approximately 2:1 Clinical presentation A rapidly increasing head circumference is the most common presentation, with symptoms usually presenting in a short time (5 days to 3 months). Seizure activity is uncommon. Radiographic features Desmoplastic infantile ganglioglioma manifests as an exceptionally large cerebral hemispheric mass composed of both cystic and solid portions. The frontal and parietal lobes are the most common sites. CT The solid portion of these large masses is typically slightly hyperattenuating and usually located along the cortical margin of the mass. Following administration of contrast, these masses usually enhance intensely, and may demonstrate a dural tail. Calcification is not a ...

Epithelial-myoepithelial carcinoma (EMC) is a malignant salivary gland neoplasm comprised of a biphasic arrangement of inner luminal ductal cells and outer myoepithelial cells. Adenoid cystic carcinoma (AdCC) is also a biphasic tumor comprised of ductal and myoepithelial cells, but these components tend to be arranged in a more cribriform pattern. The occurrence of "hybrid carcinomas" that show mixed patterns of EMC and AdCC raises questions about the relationship of these morphologically overlapping but clinically distinct tumors. AdCCs frequently harbor MYB-NFIB gene fusions. Mapping of EMCs (including hybrid forms with an AdCC component) for this fusion could help clarify the true nature of EMC as a distinct entity or simply as some variant form of AdCC. Twenty-nine cases of EMC were evaluated including 15 classic low-grade EMCs, 7 intermediate-grade EMCs, 2 EMCs with myoepithelial anaplasia, 1 EMC with high-grade transformation, and 4 hybrid EMCs with an AdCC component. Break apart ...

Cystadenocarcinoma is a malignant form of a cystadenoma and is a malignant neoplasm derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur. Cystadenocarcinomas develop frequently in the ovaries, where pseudomucinous and serous types are recognized. Similar tumor histology has also been reported in the pancreas, although it is a considerably rarer entity. It is the most common malignant ovarian tumor.[citation needed] Contains complex multi-loculated cyst but with exuberant solid areas in places. It usually presents with omental metastases which cause ascites. Papillary serous cystadenocarcinoma "Female Genital Pathology". Retrieved 2009-03-23.

To identify reliable predictors of outcome in comatose patients after cardiac arrest using a single routine EEG and standardized interpretation according to the terminology proposed by the American Clinical Neurophysiology Society.In this cohort study, 4 EEG specialists, blinded to outcome, evaluated prospectively recorded EEGs in the Target Temperature Management trial (TTM trial) that randomized patients to 33°C vs 36°C. Routine EEG was performed in patients still comatose after rewarming. EEGs were classified into highly malignant (suppression, suppression with periodic discharges, burst-suppression), malignant (periodic or rhythmic patterns, pathological or nonreactive background), and benign EEG (absence of malignant features). Poor outcome was defined as best Cerebral Performance Category score 3-5 until 180 days.Eight TTM sites randomized 202 patients. EEGs were recorded in 103 patients at a median 77 hours after cardiac arrest; 37% had a highly malignant EEG and all had a poor outcome

Desmoplastic infantile gangliomas (DIGs) are rare brain tumors that are normally located in the frontal or parietal lobes of the brain. They are usually diagnosed before 18 months of age with most infants presenting with a short duration of symptoms. Although seizures are not commonly observed, a bulging fontanelle, rapid head growth, vomiting, and a sunset sign are usually noted. The standard treatment for DIGs is surgical resection (surgical procedure in which the portion of the brain with the tumor is removed ...

PURPOSE: To document differences in color Doppler flow and gray-scale ultrasonographic (US) features between benign and malignant axillary lymph nodes in women with primary breast cancer. MATERIALS AND METHODS: The longitudinal-transverse axis ratio and hilar status on color Doppler flow and gray-scale US images were prospectively studied for each of 145 axillary nodes in 135 women (74 palpable nodes in 69 women, 71 nonpalpable nodes in 66 women) with primary breast cancer. Intranodal flow distribution was described as peripheral, central, or central perhilar. Resistive and pulsatility indexes and peak systolic velocity were documented. For comparison of benign and malignant features, nodes were divided into three groups: palpable and nonpalpable, palpable, and nonpalpable. RESULTS: Color flow was demonstrated equally well in benign and malignant axillary lymph nodes for all three groups. For all nodes, peripheral flow was significantly higher in malignant (118 of 153 nodes [77%]) than benign ...

DIAGNOSIS: MALIGNANT SOLITARY FIBROUS TUMOR DISCUSSION. The solitary fibrous tumor was first described as a pleural lesion but has subsequently been reported in numerous extrathoracic sites. Meningeal examples have been reported but are rare (1,2,4,5). Extrathoracic malignant solitary fibrous tumors are extremely rare and have not been reported previously intracranially. Anaplastic features including areas of increased cellularity, necrosis, nuclear atypia, and greater than 4 mitoses/10 high power fields are felt to be associated with aggressive behavior (6) although the collective experience is limited.. The differential diagnosis includes hemangiopericytoma, anaplastic meningioma and malignant fibrous histiocytoma. As with any poorly differentiated tumor, cell lineage must be extensively investigated using immunohistochemistry and electron microscopy. CD34 immunostaining is helpful in distinguishing solitary fibrous tumors from other considerations. Solitary fibrous tumors display diffuse ...

see Chapter IV). Leukoplakia is a white plaque that cannot be removed by gentle scraping and for which no other etiology can be identified. Microscopically, leukoplakias exhibit hyperplasia of keratinocytes, as represented by hyperorthokeratosis, hyperparakeratosis, and/or acanthosis. The term dysplasia is reserved for lesions showing combinations and degrees of cytologic atypia (e.g., hyperchromatism, increased nuclear size, pleomorphism, dyskeratosis, and increased or (1,18) abnormal mitotic figures). Atypia confined to basilar and parabasilar keratinocytes constitutes mild dysplasia , whereas atypia extending into the midspinous layer is termed moderate dysplasia. When cellular atypia extends to the surface layer, the terms severe dysplasia and carcinoma in situ (complete top-to-bottom cytologic atypia) are applied. Architectural changes are also a feature of dysplasia, the most significant being a bulbous or teardrop shape of rete ridges. For oral mucosa in general, up to 20% of clinically ...
