objective: oral non- hodgkin’s lymphoma (nhl) is a relatively rare neoplasm that may develop in the soft tissues or jaw bones, with or without node or marrow involvement. oral lymphomas are often difficult to diagnose as there are no characteristic clinical features and usually appear as non-tender swellings.   case: we describe clinical, radiographic, histopathological and immunohistochemical ...

primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

argyrophilic nucleolar organizer regions (agnors) were determined in 94 pleural, pericardial and peritoneal effusions. the results were correlated with cytologic diagnosis to determine the diagnostic potential of this technique. cytologically the number of normal, reactive and malignant effusions were 32, 28 and 34 respectively. the mean agnor counts for normal, reactive and malignant specimens...

conclusion serum cyfra21-1 is useful as a measure in differentiating malignant from benign pleural effusion. results there was statistically significant difference between mean of serum cyfra21-1 levels of benign (3.9±7.6) and malignant(19.5± 30) pleural effusion (p=0.01). in addition the sensitivity, specificity, positive predictive value and negative predictive value of serum cyfra21-1 at the...

Background: Ovarian cancer is the fifth most common cancer in woman and the fifth most frequent cause of cancer death. Ovarian cancers are usually asymptomatic until metastasized, patients have advanced disease at diagnosis in more than 2/3 of the cases. Totally 75-80 % of ovarian masses are benign. The strongest patient related risk factor for ovarian cancer is increasing age. The most ovarian...

Introduction: There is still no finding available that can show the malignant clinical course in patients with middle cerebral artery stroke. The aim of this study was to compare Doppler ultrasound findings in patients with malignant and non-malignant middle cerebral artery stroke in order to obtain its prognostic value in detecting malignant course. Method:</stro...

Neuroleptic malignant syndrome (NMS) is a rare but life-threatening idiosyncratic side effect resulting from neuroleptic drugs. NMS mainly occurs in patients treated with high-potency typical antipsychotics, but rarely caused by atypical antipsychotics. Although NMS is less common with atypical antipsychotic, but it seems that its incidence is rising due to increased administration of such drug...

melanoma of the oral cavity is a rare malignant disease. on account of the presence at relatively obscure areas in the oral cavity, most of oral malignant melanomas are diagnosed at a late stage. early diagnosis is essential for successful treatment and perhaps is the key factor in improving the prognosis of oral malignant melanoma. however, no large clinical series exist, and in fact, clinical...
