A leiomyosarcoma of the prostate detected incidentally by the annual medical checkups

The patient was a 72-year-old man who was pointed out high PSA by annual health check, but had not pollakisuria, pain on voiding or any other urologic symptoms. His PSA was 9.0 ng/ml. Ultrasonography and MRI showed a protruding tumor from the left lobe of the prostate. A histological examination of biopsy specimens revealed lieomyosarcoma of the prostate. Total prostatectomy was performed and no adjuvant therapy was done. He is well for three months after surgery without any clinical evidence of recurrence. 63 cases of prostatic lieomyosarcoma reported from Japanese literature were reviewed.
