Abstract

A liposarcoma is the most common soft tissue sarcoma in adults with an incidence of betwen 9.8 and 16% of all soft tissue sarcomas. Among the various histological types, a dedifferentiated liposarcoma has rarely been reported. We experienced a case of a giant 7 kg dedifferentiated liposarcoma arising in the mesentery of a 57-year old male patient. Abdominal computed tomography showed a huge lipoid mass occupying the whole abdomen. A surgical excision was carried out. Histologically, the tumor was composed of a well-differentiated liposarcomatous area and a leiomyosarcoma-like dedifferentiated area. The authors reviewed the prognostic factors and treatments for a liposarcoma.
