Abstract

Sarcomatoid carcinoma of the prostate is a rare variant of prostatic cancer, with less than 100 cases reported in the literature up to date. Tumors are most commonly composed of an admixture of both malignant glandular and spindle cell elements. The sarcomatoid component can vary from 5 to 99%. We report a case of a 76-year old Caucasian man who underwent transurethral resection of the prostate for the treatment of bladder outlet obstruction. Histopathologic examination revealed a tumor with malignant epithelial and sarcomatous elements. The malignant epithelial component consisted of poorly differentiated adenocarcinoma (Gleason score 5+4=9/10) and the sarcomatous component was mainly composed of undifferentiated spindle cells. On immunohistochemistrythe latter expressed a positive staining for vimentin. Several cells were positively stained for cytockeratin AE3 and myoD1 while all were negative for actin, desmin and myogenin. The diagnosis of sarcomatoid carcinoma was finally made. Although sarcomatoid carcinoma of the prostate is a highly aggressive neoplasm and patients have a poor prognosis, our patient is still alive one year after diagnosis.
