title: Primary signet ring cell adenocarcinoma of the prostate: a case report and literature review.
abstract: We report a rare case of primary signet ring cell adenocarcinoma of the prostate in a 61-year-old male, who died of systemic lymphatic spread. Autopsy ruled out another primary signet ring cell adenocarcinoma outside the prostate. However, immunohistochemically, the tumor stained negatively for prostate-specific antigen. A review of the literature revealed only 15 case reports, including our case.
