An ovarian carcinoid tumor is rare and is classified as a borderline malignant tumor. We report a case of stromal carcinoid tumor arising in a mature cystic teratoma of the ovary, which was managed with diagnostic and therapeutic laparoscopic surgery. A 31-year-old woman with constipation had a right ovarian tumor identified on a postnatal medical examination. Magnetic resonance imaging revealed a 10-cm tumor in the right ovary with multiple cystic components. We performed a laparoscopic right salpingo-oophorectomy. Histological analysis showed that the right ovarian mass contained stromal carcinoid tumor in a mature cystic teratoma. In conclusion, although an ovarian tumor demonstrates characteristics typical of a mature cystic teratoma, accompanied by constipation, it may include small borderline malignant lesions. In general, ovarian carcinoid tumors are slow growing, and have a good prognosis, but some cases of metastasis or recurrence have been reported. Therefore, these borderline tumors require careful evaluation
