A CASE OF LIPOSARCOMA OF THE GREATER OMENTUM

An extremely rare case of primary liposarcoma of the greater omentum is reported. A 51-year-old man was seen at the hospital because of abdominal distention. As a result of close examinations, the patient was diagnosed as having an intraabdominal tumor and was operated on. Upon laparotomy, a large volume of ascites was noted. The tumor was mainly present in the greater omentum, but a large number of small tumors with the diameters of 1 to 2cm were confirmed in the entire abdomen. The tumors were extirpated as possible as we could. The histopathological diagnosis was well differentiated liposarcoma partly with myxoid change. The prognosis was poor. The patient experienced recurrence four months after the operation and died after unsuccessful chemotherapy.
