A light and electron microscopic study of a hemangiopericytoma of the prostate with local extension.
A case of primary hemangiopericytoma of the prostate is reported. The patient presented with obstructive uropathy and was diagnosed as "benign prostatic hypertrophy." A transurethral resection was done and was diagnosed as "cellular leiomyoma." Obstructive symptoms recurred and skin and pubic bone involvement appeared 2 months later. Light and electron microscopy of the repeat transurethral resection and biopsy of the perineal mass confirmed the diagnosis of hemangiopericytoma of the prostate.
