title: Leydig cell tumor of intra-abdominal testis.
abstract: A patient with bilateral cryptorchidism and gynecomastia due to Leydig cell tumor involving the left intra-abdominal testis is described. Raised serum estrogen, low serum testosterone, and ultrasonic demonstration of a tumor in the left testis allowed the diagnosis to be suspected preoperatively. The relevant literature is reviewed.
