Tumor of lipomatous origin in the ovary is exceedingly rare. We report a case of incidental lipoma in the right ovary in a 41-year-old female with a contralateral borderline serous tumor. It is important to identify such isolated incidental lipoma to differentiate it from other liposarcoma and teratomatous elements.

We present two cases of nine and twenty-seven years old girls with recurrence of immature teratoma after an incomplete surgical staging. In both cases, there were huge abdominopelvic masses despite decrease in tumor markers with chemotherapy. Complete surgical resection of these masses was done, and histopathology showed only mature teratoma.
