Immunohistochemistry have had a huge impact on oral and maxillofacial pathology diagnosis. As method it determines distribution amount of certain cellular molecules via specific antigen-antibody reaction. Whereas in most cases definitive diagnosis is achieved based detailed hematoxylin eosin cytomorphological analysis, along with clinical radiological features, some challenging equivocal neopla...

primary fallopian tube carcinoma is a rare tumor that histologically and clinically resembles epithelial ovarian cancer. here we introduce a case of tubal carcinoma in a postmenopausal woman. the diagnosis of primary fallopian tube carcinoma is rarely considered preoperatively and is usually first appreciated by the pathologist. because of low frequency of tubal carcinoma, there are few systemi...

abstract background: cholesterol cleft granulomas with clusters of giant cells were noted to be a common feature of non-specific interstitial pneumonia (nsip). objective: this study aimed to define the cell populations involved in the granulomas. methods: the granulomas of 16 patients with cryptogenic fibrosing alveolitis (five cases with the histological features ofnsip, five with those ofuip ...

undifferentiated nasopharyngeal corcinoma is frequently misdiagnosed as large cell malignant lymphoma. the aim of this study is to evaluate the diagnostic role of immunohistochemistry and electron microscopy in this tumor. 81 cases of nasopharyngeal carcinoma were studied. patients ranged from 9-90 years in age (mean: 48.5 years). the age incidence curve was bimodal with two peaks in 2-3 and 5-...

uterine lymphoma is a rare disease therefore, information regarding histologic type, immunophenotype of tumor cells and etiologic factors are limited. although secondary involvement of the genital tract occurs in up to 40% of cases• of disseminated lymphoma, lymphoma presenting with primary female genital tract . symptomatology is very unusual. we report a case of b-cell lymphoma in the uterine...

twelve (experiment i) and four (experiment ii) multiparous dairy cows seronegative to pestivirus were selected and randomly assigned to either a control group which did not become infected or a treatment group in which all cows became infected following intranasal inoculation 9 days before ai. the experimental induction of infection was carried out with 2 ml of non-cytopathic pestivirus (bvd vi...
