Benign soft-tissue neoplasm simulating sarcoma of spermatic cord.

A large, painless, slow-growing mass arising in the scrotum of a twenty-three-year-old man, which proved to be benign myxoma, simulated a primary sarcoma of the spermatic cord. Only 1 case of myxoma involving the spermatic cord has been reported previously. It is extremely important that multiple microscopic sections of the specimen be examined carefully so that the proper tissue diagnosis can be made. A false diagnosis of malignancy may lead to treatment that is not indicated and that has a high morbidity.
