The purpose of this study was to analyze the significance of p53, bcl-2 and EGFR expression in the grading and biological behavior of astrocytic tumors, especially in the Indian population. A total of 117 cases of astrocytomas graded using the WHO grading system published in 2007 were immunolabeled using p53, EGFR and bcl-2 monoclonal antibodies and(More)
BACKGROUND The MIB-1 labeling index (LI) has proved to be useful in assigning grading and prognosis to astrocytomas. The purpose of our study was to analyze the utility of MIB-1 LI in differentiating astrocytomas of varying grades and the possible relationships of MIB-1 LI with clinical parameters like age and sex. We also wanted to study the prognostic(More)
BACKGROUND The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis.

Globally, peripheral T-cell lymphomas (PTCLs) constitute about 12% of all non-Hodgkin lymphomas, of which the unspecified category is the most common subtype (30%). Mostly, the unspecified category shows a diffuse pattern of involvement in the lymph nodes. However, rarely, they may show a follicular/nodular pattern mimicking a follicular lymphoma. We report(More)
Primary non-Hodgkin lymphomas of the oral region are rare, accounting for 3-5% of all malignant lesions. Of these, peripheral T-cell lymphomas (PTCLs) are extremely rare with only a few cases reported in literature. We describe a case of 50-year-old female who presented with an indurated lesion on the tongue. PTCL was diagnosed after immunohistochemical and(More)
