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.
