LIPOSARCOMA OF THE COLON PRESENTING AS AN ENDOLUMINAL MASS

Background:Liposarcoma is one of the most common soft tissue sarcomas of adult life, usually occurring in the retroperitoneum and the extremities. Primary liposarcoma of the colon is very rare. The optimal treatment has not been established due to the small number of cases reported. We report a case of primary liposarcoma of the colon presenting as an intraluminal lesion.

Case presentation: A 47-year-old female presented with abdominal pain, loose stools and hematochezia associated with fatigue for 2 weeks duration. An ultrasonogram detected a heteroechoic lesion of size 3.8*4.4 cm in the epigastric region related to the bowel. A contrast enhanced computed tomography identified a well-defined predominantly fat attenuating lesion associated with transverse colon. The patient underwent surgical resection of the lesion with end-to-end colo-colic anastomosis. Pathologic examination was consistent with well differentiated liposarcoma of the colon.
