AMH and testicular granulosa cell tumor: AMH expression has been shown in overt Sertoli cell tumors [73, 74], in large cell calcifying Sertoli cell tumors frequently associated with Peutz-Jeghers syndrome [74], in primary or metastatic granulosa cell tumors of the testis [73], and in intratubular Sertoli cell proliferations, which has been suggested to represent an “in situ” or early stage of Sertoli cell tumors [74].
