Abstract

卵巢成熟性囊性畸胎瘤癌变(malignant transformation of ovarian mature cystic teratoma,MCT)较罕见。本文报道1例卵巢成熟性囊性畸胎瘤,灶区伴小细胞神经内分泌癌混合鳞状细胞癌变(小细胞癌约占60%,鳞状细胞癌约占40%)。本例小细胞癌区域CD56、突触素阳性以及Ki-67阳性指数高表达至80%,p40、细胞角蛋白(CK)5/6阴性,提示神经内分泌癌分化;鳞状细胞癌癌变区域p40、CK5/6阳性,CD56、突触素阴性;两种癌变区域p53及p16均阴性。该疾病主要与宫颈或阴道的鳞状细胞癌、胃肠道低分化腺癌、泌尿系统的尿路上皮癌、呼吸道及胃肠道小细胞癌转移、卵巢粒层细胞瘤相鉴别。此病以手术全切除为主,术后辅以系统性放、化疗。.
