Metastasis of gastric adenocarcinoma to the prostate gland is extremely rare. Herein, we report a case of gastric adenocarcinoma in a 56-year-old man with prostatic metastasis diagnosed through the analysis of biopsy specimens from representative lesions in the stomach and prostate gland. Immunohistochemistry of the prostatic tissue showed positive staining for cytokeratin 7 and negative staini...

Introduction: Prostate cancer is the second common malignancy in men. Prostatic intraepithelial neoplasia (PIN) precursor lesion of prostatic carcinoma. Histopathological examination necessary to diagnose PIN lesions. Objective: The aim study determine incidence and analyse usefulness basal cell marker p63 expression various lesions prostate. Methods: This a two-year prospective 65 transurethra...

Brain and Head and neck metastases are rare in prostatic carcinoma patients. In this report we present a very uncommon case of the concomitant occurrence of a prostatic adenocarcinoma with neck metastases and an advanced laryngeal squamous cell carcinoma without neck metastases. The presence of cervical lymph node prostate adenocarcinoma metastasis concomitantly with a laryngeal squamous cell c...

INTRODUCTION A collision tumor is the meeting and eventual intermingling of two malignant neoplasms arising from independent topographical sites. Collision metastasis of carcinomas in the lymph nodes is a rare event. A literature search revealed only three cases of such a collision metastasis of prostatic and urothelial carcinoma, and only one of those cases had used immunohistochemical stains ...

Introduction: Prostate cancer is a multifaceted disease comprises distinct biological subtypes with varied spectrum of clinical, pathologic and molecular features with different prognostic and therapeutic implications. Over the last few decades there have been outstanding advances in prostate cancer management leading to earlier detection of disease. Prostatic cancer diagnosis is based on a com...

Hexosaminidase activity in prostatic tissue has been compared in 15 patients with benign prostatic hyperplasia and 15 patients with prostatic carcinoma. The ratio of enzymatic activity for the two substrates tested (p-nitrophenyl-2-acetamido-2-deoxy-beta-D-glucopyranoside and p-nitrophenyl-2-acetamido-2-deoxy-beta-D-galactopyranoside) was not significantly different in the two groups of patient...

Background: Prostatic carcinoma is one of the most important causes of mortality in elderly men mainly because of the late detection despite of the fact that it is a potentially curable disease. Fine needle aspiration cytology (FNAC) is an easy to perform outpatient procedure requiring no expensive equipment or anesthesia. Objectives: The present study was carried out in an attempt to evaluate ...

An immunocytochemical assay using a monoclonal antibody to estro gen receptor was applied to frozen sections of 43 prostatic tumors. In addition, in 16 tumors the results of the immunocytochemical assay were compared with those obtained using an enzyme immunoassay for estrogen receptor, a tritiated ligand binding assay, and a histochemical procedure using fluorescein-labeled estradici conjugate...

BACKGROUND High-grade prostatic intraepithelial neoplasia (HGPIN) is currently the only recognized premalignant lesion of prostatic carcinoma. METHODS This review article discusses HGPIN, its link to prostatic adenocarcinoma, and the significance of its presence on needle biopsy. The criteria and clinical impact of the diagnosis of atypical small acinar proliferation on needle biopsy are revi...

A patient with known prostatic cancer presented with bilateral orbital masses. On CT there was a bulky soft-tissue mass in the cranial aspect of each orbit. An open biopsy revealed undifferentiated tissue that stained strongly positive for prostatic-specific acid phosphatase, confirming the diagnosis of metastatic prostate carcinoma.
