  Ovarian carcinoids represent 0.1% of all ovarian cancers. We report a case of primary ovarian carcinoid with a mature cystic teratoma diagnosed after laparoscopic surgery. A 32-year-old woman presented with secondary amenorrhea. Pregnancy test was negative. Ultrasonography and magnetic resonance imaging revealed a mature cystic teratoma measuring 7 cm in the right ovary. We performed a laparoscopic right ovarian cystectomy. The pathological examination revealed that most of the tumor was a mature cystic teratoma, including a small focal lesion of a trabecular carcinoid tumor. Therefore, a laparoscopic right salpingo-oophorectomy was performed, and the postoperative pathology indicated no tumor tissue. The prognosis of ovarian carcinoids is favorable; however, careful postoperative follow-up is important because recurrence may happen in a small number of cases.
