A 71-year-old man presented with sudden abdominal pain. He had past history of atrial fibrillation, cerebral infarction and heart-valve replacement and received anticoagulant therapy with warfarin. Computed tomography of the abdomen revealed bloody ascites and a huge mass in contact with the third portion of the duodenum. The mass was encapsulated and consisted of a solid component with calcification and hematoma. Under the preoperative diagnosis of gastrointestinal stromal tumor with intra-abdominal bleeding, laparotomy was performed. Intraoperative findings revealed the tumor arising from the right mesocolon and excision of the tumor with right hemicolectomy was performed. Histologic examination confirmed a diagnosis of mixed type liposarcoma. No postoperative complication was observed and he was discharged home on the 8th postoperative day. He remains alive and well with no evidence of disease 52 months after resection.
