[Multiple primary tumors complicating prostatic cancer]

Postmortem examination of 600 cases of prostatic cancer established concomitant malignancies at other sites in 3.5%, the latter being mostly gastrointestinal carcinomas. Most tumors were synchronous, whereas only 4 out of 21 were metachronous ones. Among the 17 cases of synchronous tumors, prostatic carcinoma was the main pathology in 11, competing-2 and a concomitant one in 4 cases. Out of 17 cases, both tumors were diagnosed intravitally only in 4, one tumor-8 and none-in 5 cases. Among 32 (5.3%) cases of concomitant benign lesions, there was one in which bleeding from an ulcerated glomus tumor of the stomach was the immediate cause of death.
