A case is presented of widely metastatic choriocarinoma, associated with an intratubular proliferation of atypical germ cells in the testis and a minute adult cystic teratoma. Immunoperoxidase study of the intratubular germ cells did not confirm their trophoblastic origin. Intratubular proliferation of undifferentiated germ cells may be associated with choriocarcinoma.
