Non-puerperal uterine inversion and uterine sarcoma (malignant mixed müllerian tumor): report of an unusual case.

A 45-year-old woman with a history of cervical cancer (stage IIa), who had received complete radiation treatment 16 years previously, presented with a huge mass protruding from her vaginal introitus. She had had the condition for about 1 week. Diagnosis was difficult, and she elected to have a diagnostic laparoscopic procedure plus tumor removal. The pathologic investigation revealed a malignant mixed müllerian tumor of the endometrium. Post-operative course was uneventful. She underwent postoperative pelvic radiation. No recurrence was found during the 13 months follow up period. This rare case of chronic non-puerperal uterine inversion due to malignant mixed müllerian tumor (MMMT) is herein reported.
