Multifocal Dedifferentiated Liposarcoma of the Jejunal Mesentery

Abdominal liposarcoma is most often located in the retroperitoneum. Small bowel mesentery is a rare site of liposarcoma. Dedifferentiated liposarcoma (DDLS) is a rare variant of mesenteric liposarcoma with only 12 cases reported in the literature. DDLS has a worse prognosis compared to a well-differentiated liposarcoma. Here, we present a case of giant liposarcoma located in the jejunal mesentery diagnosed on the contrast-enhanced computed tomography of the abdomen. The patient underwent complete surgical excision with uneventful postoperative recovery. DDLS was confirmed on histopathological examination of the resected specimen. The patient is currently receiving adjuvant therapy with doxorubicin and ifosfamide in view of close resection margin, mitotic rate and high rate of recurrence.
