Abstract

Prostatic synovial sarcomas are exceedingly rare. To our knowledge, only six primary cases have been reported so far. We herein describe a primary synovial sarcoma of the prostate seen in a 25- year-old male patient, the youngest patient seen with this disease to date. He was referred to our department with the diagnosis of high-grade sarcoma of the prostate revealed by TRUS-guided biopsy. On admission he had a transurethral catheter for acute retention of urine. MRI revealed a solid prostatic tumor of 9.5 x 8 cm involving the rectum without any evidence of lymphatic or distant metastases. The patient underwent total pelvic exenteration and sigmoid end colostomy with ileal conduit. Histopathology revealed a synovial sarcoma of the prostate, immunoreactive to vimentin, Bcl–2 and cytokeratin. The patient is doing well at 18 months follow-up.
