Leiomyosarcoma of the rectum and prostate.

A 47-year-old man with leiomyosarcoma involving the rectum and prostate was treated by radical abdominoperineal resection. This case appears to be unique in that leiomyosarcoma was present in both the rectum and the prostate. The literature is reviewed, highlighting some interesting clinical features of this condition. The prognosis for leiomyosarcoma of both rectum and prostate is poor.
