liposarcoma in uterine lipoleiomyoma

Wednesday 4 January 2012

Primary sarcomas of the uterus are uncommon, leiomyosarcoma being the most frequent. Most uterine sarcomas arise de novo, with malignant transformation of a benign mesenchymal tumor being a very rare event, and is reported only in leiomyomata.

Primary liposarcomas of the uterus are extremely rare and are most likely to arise from malignant transformation of a lipoleiomyoma .

These tumors should be added to the differential diagnosis of benign lipomatous tumors, myxoid mesenchymal tumors, and malignant mixed Müllerian tumors (if pleomorphic) of the uterus.
