Abstract

Soft tissue sarcomas are common neoplasms accounting for 1% of all adult malignancies; however, soft tissue sarcomas infrequently arise from the abdominal viscera. Many case reports discuss gastric and esophageal neoplasms. In the group of gastrointestinal liposarcomas, primary duodenal liposarcomas are among the rarest, with only three previous cases reported in the literature. Herein, we discuss a case of primary duodenal liposarcoma. A 59-year-old woman presented with symptoms consistent with anemia raising suspicion for an upper gastrointestinal bleed. Upper endoscopy revealed an ulcerated mass in the first portion of the duodenum. The patient underwent a segmental duodenal resection and distal gastrectomy with Roux-en-Y reconstruction. A diagnosis of dedifferentiated liposarcoma was rendered on the resected specimen. At 16 months' follow-up, the patient remains without evidence of disease recurrence. We have presented a case of primary duodenal liposarcoma, which is among the rarest locations for gastrointestinal sarcomas with only three previous reports in the literature. Liposarcomas should be included in the differential for submucosal masses of the duodenum.
