Recurrent liposarcomas of the abdomen and retroperitoneum: three case reports.

Abstract

We report three cases of patients with liposarcomas of the abdomen who had been treated during the last 13 years (1980-1993). Two patients were men, aged 29 and 51 years, with tumors of the retroperitoneal space and the third patient was a woman aged 64 years with a tumor in the peritoneal cavity. Therapeutic treatment was as aggressive as possible excision of the tumor. In the case of the first male patient, the histological examination revealed a retroperitoneal myxoid liposarcoma which recurred 5 times within 13 years. In the second male patient, it revealed a well differentiated retroperitoneal liposarcoma of the sclerosing type which recurred 5 times within 5 years since the first treatment. Finally, the one female patient had 2 recurrences of myxoid liposarcoma of the abdomen 9 years after the first operation, presented with an infected mass and has been well since then.
