Primary mesenteric liposarcomas are very rare, especially when they are of mixed histologic pattern. Patient prognosis is based upon the most aggressive histologic type of liposarcoma. A case is reported of a 77-year-old man with a history of slowly increasing abdominal volume over 3 years. The diagnosis of giant intra-abdominal mass suspect of liposarcoma was confirmed by computed tomography and ultrasound scans. The patient underwent resection of 24 tumor masses weighing together 23.5 kg. The microscopic diagnosis was mixed-type liposarcoma of the mesentery. Although this type of tumor is rare, tumor tissue should be thoroughly collected and analyzed on histologic examination to reach definitive diagnosis. Recognition of the underappreciated subtype of liposarcoma is important for proper prognosis and treatment of the patient. According to our knowledge, this is the largest size of mixed-type mesenteric liposarcoma described in the English literature.
