Abstract

Dedifferentiated liposarcoma (DDLPS) is a variant of liposarcoma but with a more aggressive course. It occurs most commonly in the retroperitoneum and rarely in any other anatomical location. We describe a case of DDLPS arising from the small bowel mesentery presenting as submucosal mass of the small bowel. The current case is unusual as the tumor originated from the small bowel mesentery and a dedifferentiated component transmurally invaded the small bowel wall, including the small bowel submucosa.
