Supplementary Material for: Primary Ovarian Neuroendocrine Carcinoid Tumor Arising in a Mature Cystic Teratoma

Primary ovarian neuroendocrine carcinoid tumors are extremely rare. However, their clinical course is good, and hence, fertility-sparing surgery is a feasible treatment option in cases of unilateral localized lesions. In this report, we present the case of a 20-year-old nulliparous woman who was diagnosed as having a primary ovarian neuroendocrine carcinoid tumor arising from a mature cystic teratoma. She underwent laparoscopic right ovarian cystectomy and her postoperative recovery was uneventful. The patient has been under close observation over a 1-year follow-up period and has shown no evidence of tumor recurrence.

原发性卵巢神经内分泌类癌（Primary ovarian neuroendocrine carcinoid tumors）极为罕见。然而该类肿瘤的临床预后良好，因此对于单侧局限性病灶患者，保留生育功能手术是可行的治疗选择。本报告中，我们报道1例20岁未产妇，其被诊断为起源于成熟囊性畸胎瘤的原发性卵巢神经内分泌类癌。患者接受了腹腔镜下右侧卵巢囊肿切除术，术后恢复顺利。经过1年的密切随访观察，患者未出现肿瘤复发迹象。
