A 34-year-old male was referred to us for further examination of gynaecomastia. Serum tests revealed high levels of alpha-foeto protein, human chorionic gonadotropin, oestradiol and prolactin. He had a history of testicular pain and mass, and had been under a local physician's care. With the physician's record of the course of regression we made a diagnosis of microscopic testicular tumour. Serial histopathological sections of the testis revealed a 0.8 mm lesion of chorionic and embryonal carcinoma. We discuss the course of spontaneous regression with a review of the literature.

D002822 Choriocarcinoma A malignant metastatic form of trophoblastic tumors. Unlike the HYDATIDIFORM MOLE, choriocarcinoma contains no CHORIONIC VILLI but rather sheets of undifferentiated cytotrophoblasts and syncytiotrophoblasts (TROPHOBLASTS). It is characterized by the large amounts of CHORIONIC GONADOTROPIN produced. Tissue origins can be determined by DNA analyses: placental (fetal) origin or non-placental origin (CHORIOCARCINOMA, NON-GESTATIONAL). Choriocarcinomas

D018236 Carcinoma, Embryonal A highly malignant, primitive form of carcinoma, probably of germinal cell or teratomatous derivation, usually arising in a gonad and rarely in other sites. It is rare in the female ovary, but in the male it accounts for 20% of all testicular tumors.
