Primary liposarcoma of the jejunum.
The rare case of a primary liposarcoma of the jejunum in a 52-year-old man is described. The main tumor mass was located within the submucosa and caused chronic subileus by subtotal obstruction of the jejunum. The histology showed a mixed type liposarcoma. In the main mass features of well differentiated lipoma-like and sclerosing liposarcoma predominated. In the tumor periphery they were combined with areas of pleomorphic liposarcoma, consisting of tightly packed giant lipoblasts. After an incomplete resection well differentiated sclerosing and pleomorphic liposarcoma recurred within the intestinal wall and in the mesentery near the primary anastomosis. The unusual primary site and pattern of spread of the tumor are discussed and the literature is reviewed.
