Intratubular Germ Cell Neoplasia
Intratubular germ cell neoplasia in a cryptorchid testis. The tubular basement membrane is thickened considerably. The interstitium contains sheets of Leydig cells. The patient was a 30 y/o male with history of cryptorchidism which had been corrected at age 4; however, the testis retracted into the inguinal canal as he grew older.
