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.
