Abstract

Carcinosarcoma (CS) or Sarcomatoid carcinoma (SC) of the prostate is a very rare malignant tumor of the prostate having an aggressive clinical course and dismal prognosis. The adenocarcinomatous element is usually of the acinar type and closely admixed with a sarcomatous component. We report a case of α-methyl-CoA-racemase (AMACR)-negative pseudohyperplastic variant of adenocarcinoma in CS. To the best of our knowledge, there have been no published case reports of this variant in CS till date. An accurate diagnosis is essential as this uncommon, aggressive cancer has limited therapeutic options.

KEYWORDS:
