title: [Leydig cell, Sertoli cell and adult granulosa cell tumors].
abstract: According to the World Health Organization (WHO) classification Leydig cell tumors, Sertoli cell tumors and granulosa cell tumors of the testes belong to the group of sex cord-stromal tumors. These tumors most frequently occur sporadically but in rare cases can be associated with syndromes. These tumor entities show characteristic morphological changes, which in combination with specific immunohistochemical markers facilitate the diagnosis. Recent results of molecular pathological investigations, especially beta-catenin mutation analysis, allow a better categorization of these tumor entities.
