We investigated 40 cases of renal cell carcinoma (RCC) to study the polysomy 7 status in papillary and clear-cell types (nonpapillary RCC) and relationship with clinical, pathological, and biological features such as grade, stage, tumor proliferation rate (PCNA expression) and epidermal growth factor receptor (EGFr) expression and thereby to understand the(More)
A case of peritoneal mesothelioma displaying unusual morphology, occurring in a 53 year old woman is described. The role of immunohistochemistry and electron microscopy in the evaluation of this tumor is stressed. The appropriate terminology to be used and possible etiologic factor are also discussed.
The prognostic associations of c-erbB-2 gene amplification analysed by dot-blot hybridization and of c-erbB-2 protein overexpression assessed by immunohistochemistry (IHC) were compared in 161 patients with operable breast cancer using formalin fixed paraffin embedded archival tissues. The efficiency of the dot-blot technique to detect c-erbB-2(More)

OBJECTIVE To develop a novel method for processing of fine needle aspirates subjected to electron microscopic (EM) study. STUDY DESIGN Included 70 cases of poorly differentiated malignant tumors in which a definitive diagnosis was not possible on light microscopic (LM) examination and that thus required application of an ancillary technique such as(More)
