Mature cystic teratomas (MCTs) are common benign tumors of the ovary. Coexistence of a carcinoid tumor inside an MCT is extremely rare. We present a 40-year-old woman who had intermittent abdominal pain and urinary frequency. An adnexal mass was detected during physical examination. Ultrasound indicated a 12.3 cm × 10.7 cm left ovarian mass. Surgical excision of the mass was performed, and histopathological examination revealed an MCT with three germ layers. The microcarcinoid tumor arising from an MCT showed a cord to trabecular pattern. The pathological diagnosis was a trabecular carcinoid tumor arising in an MCT. The patient did not present with carcinoid syndrome, and no recurrence was observed after 12 months of follow-up.
成熟囊性畸胎瘤（MCTs）是卵巢常见的良性肿瘤。MCT内并存类癌肿瘤极为罕见。我们报告一名40岁女性，她有间歇性腹痛和尿频症状。体格检查时发现附件区有包块。超声显示左侧卵巢有一个12.3 cm×10.7 cm的包块。对该包块进行了手术切除，组织病理学检查显示为一个具有三个胚层的MCT。起源于MCT的微类癌肿瘤呈条索状至小梁状结构。病理诊断为MCT内发生的小梁状类癌肿瘤。该患者未出现类癌综合征，随访12个月后未观察到复发。
