title: Cystic mature teratoma and epidermoid cyst associated with granulosa cell tumour: a rare ovarian scenario. Two case reports and review of the literature.
abstract: We describe two cases of association between an ovarian granulosa cell tumour and a cystic mature teratoma and an epidermoid cyst. These are very rare combinations that might lead to incorrect diagnostic interpretation, since the simultaneous presence, on routine gross and microscopic examination, of a cystic squamous lesion, intimately connected with (case 1), or contralateral to (case 2) a solid, histologically trabecular or microfollicular tumour, might suggest a diagnosis of a carcinoid tumour in a mature cystic teratoma. The differential diagnostic problems and a review of the literature are presented.
