[Giant retroperitoneal liposarcoma: report of a case].

Liposarcoma is a rare and primary malignancy developed from mesenchymal tissue. We report the case of a 32-year-old woman who had a complete exeresis of a 15 cm retroperitoneal myxoid liposarcoma. Three months later, a 9 cm local recurrence was excised and radiotherapy was performed. In 2000, a local recurrence and an intestinal localisation of the liposarcoma were observed. The retroperitoneal tumor could not be removed and she had an intestinal resection followed by chemotherapy. With the literature data, we review the pathological, therapeutic and prognostic aspects of this tumor.
