A rare case of jejunal mesenteric liposarcoma, which developed 5 years after resection of a left femoral liposarcoma (myxoid type), is reported. A 49-year-old man was referred to our hospital with left abdominal pain. Computed tomographic findings showed a tumor originating in mesenteric soft tissues, and superior mesenteric arteriography revealed not a tumor stain but arterial encasement. Laparotomy revealed a jejunal mesenteric tumor about 40 cm distant from Treitz's ligament. The tumor was completely resected and histopathological findings indicated a liposarcoma (myxoid type). The postoperative course was uneventful. On the basis of the clinical course and laboratory data, this was believed to be a case of heterochronous double liposarcoma.
