[Therapeutic problems of intra-abdominal liposarcoma].

Intra-abdominal liposarcomas are very rare tumors. We present our personal experience with one case of mesenteric liposarcoma which had perforated into the peritoneal cavity, occurring in a seven-month pregnant female patient. Seven years later, the patient is doing well. The authors have carried out a review of the literature. In addition to liposarcomas of the mesentery and the mesocolon, they observed some cases of liposarcoma localized in the omentum and the stomach; other abdominal localizations occurred sporadically. Radical surgical excision was the choice treatment. Both the propensity for locoregional spread and the histological diversity set the conditions for prognosis; the latter seemed minimally influenced by either radio- or chemotherapy.
