[Liposarcoma of the transverse mesocolon--a case report]

Primary mesenteric liposarcoma is a rare neoplasm. We experienced a case of liposarcoma of transverse mesocolon. In our case, the examination of ultrasonography and CT scan revealed the tumor was solid and encapsulated. Preoperatively we suspected the tumor was malignant by the angiographic findings. Laparotomy revealed that the tumor was located in the transverse mesocolon and it could be removed easily. The histopathological diagnosis was myxoid type liposarcoma. It is said generally that liposarcoma is liable to recur after simple resection, therefore, we reconsider that we should have excised more extensively for this case. The patient is doing well without evidence of recurrence for 17 months after operation.
