RESUMEN
Primary ovarian carcinoid tumors usually arise in association with gastrointestinal or respiratory epithelium, which is present in mature cystic teratoma. One case of carcinoid tumor arising from ovarian mature cystic teratoma is presented with a brief review of the literatures. Right ovarian solid tumor was detected incidentally in a 28 year-old woman complaining foul odor vaginal discharge. Explorative laparotomy was done on 20th Feb. 2004. There was no ascites or adhesions, but fetal head sized and dermoid natured tumor was found on right ovary, and follicular cyst, on left ovary. Bilateral ovarian cystectomy was done, and she was discharged 7 days later without any problem. One third of the reported cases have been associated with the typical carcinoid syndrome, despite the absence of metastasis. The prognosis after excision of the primary tumor is favorable, and in most cases a cure results.
