Immunohistochemical differential diagnosis between urothelial carcinoma and prostate adenocarcinoma among Egyptian patients.

The aim of the present study was to differentiate between prostate adenocarcinoma and urothelial carcinoma among Egyptian patients by immunohistochemical methods. Two groups of patients were used: urothelial group, consisted of 9 cystitis, 21 transitional cell carcinoma (TCC) and 5 urinary bladder mucoid adenocarcinoma (MAC) and prostatic group, consisted of 9 nodular prostatic hyperplasia (NPH) and 21 prostatic adenocarcinoma (PAC). H-E stained sections were performed to confirm the diagnosis and evaluate the histopathological characteristics of the tumor.

Immunohistochemical expression of GPR30 in breast carcinoma of Egyptian patients: an association with immunohistochemical subtypes.

Breast carcinoma in Egyptian women is a biologically more aggressive disease than those diagnosed in Western women, although a substantial number of cases are hormone responsive. G protein-coupled receptor-30 (GPR30), a seven transmembrane domain protein, is currently recognized as an estrogen receptor. This study aimed at evaluating the expression of GPR30 in breast carcinomas of Egyptian patients and its association with clinicopathologic parameters and immunohistochemical subtypes of breast carcinoma.
