Mature cystic teratoma and concomitant adult granulosa cell tumor (AGCT) of the ovary is a rare condition. We report a case of mature cystic teratoma and concomitant AGCT of the ovary, which was treated by laparoscopic surgery. A 64-year-old woman presented to our hospital with postmenopausal irregular vaginal bleeding. Imaging tests revealed endometrial thickness, as well as a left ovarian tumor measuring 6 cm in diameter. Preoperative investigations including endometrial tissue biopsy and imaging tests did not reveal any evidence of malignancy. We performed successful laparoscopic surgery with a meticulous technique to prevent ovarian tumor rupture. Histopathological examination of the resected specimen showed findings of AGCT and concomitant mature cystic teratoma. The tumor was localized only to the left adnexa without intraoperative tumor rupture; therefore, the patient was deemed suitable to undergo regular follow-up, which is currently ongoing without evidence of recurrent AGCT.
