摘要

Primary mesenteric liposarcoma is a rare neoplasm. Here, we report the case of a 50 year old Indian man with a pleomorphic liposarcoma of the mesentery. The clinical findings pointed towards a retroperitoneal growth but imaging resolved the issue. A laparotomy was performed and a 20 cm × 20 cm multilobulated tumour arising from the mesentery and weighing 1.8 kilograms was excised with a segment of jejunum. The cut surface had a variegated appearance with regions of necrosis. The histological features were suggestive of pleomorphic liposarcoma. Tumour cells were positive for S-100 and negative for SMA/Desmin. Complete resection is curative although the role of chemotherapy remains to be established.
