Bilateral ovarian mixed epithelial adenocarcinoma in a postmenopausal woman with unilateral ovarian yolk sac tumor component

摘要

Ovarian yolk sac tumors (YSTs) usually occur in the young women and have been rarely documented in perimenopausal and postmenopausal women. The different age distribution supposes their complex nomenclature and histogenesis. We report a case of bilateral ovarian epithelial carcinoma with right ovarian YST component in a postmenopausal woman. The patient was treated by surgery and adjuvant combination chemotherapy of taxol and carboplatin for 6 courses and has been clinically free of tumor for 6 months. The correlation between the YST and the epithelial components always confuse us. Ovarian yolk sac tumors are not a discrete entity and represent a multifaceted group of neoplasms. The conjunction of multi antibodies help in differential diagnoses. In addition to a thorough case description, the literature concerning this entity is reviewed and discussed.
