腹腔鏡下手術後に診断された成熟嚢胞性奇形腫合併卵巣カルチノイドの1例

Abstract

An ovarian carcinoid tumor is extremely rare; the incidence is about 1.3% of all carcinoid tumors. A case of a primary ovarian carcinoid tumor with a mature cystic teratoma diagnosed after laparoscopic surgery is presented. The patient is a 35- year-old gravida 2, para 2 who was diagnosed with a left ovarian tumor during her second pregnancy. Magnetic resonance imaging (MRI) revealed a mature cystic teratoma. In the third postpartum month, she underwent a laparoscopic assisted ovarian cystectomy. The pathological examination revealed that most of the tumor was a mature cystic teratoma, including a small focal lesion of insular carcinoid tumor, which showed a positive reaction with chromogranin- A. Therefore, a laparoscopic left salpingo-oophorectomy was performed. Although the prognosis of this tumor is favorable, careful periodic examinations might be necessary because a small number of cases can recur.
