title: Giant primary mesenteric liposarcoma: a rare case report.
abstract: Primary mesenteric liposarcoma is a rare malignant tumor of mesenchymal origin. These tumors are often found to be of substantial size upon first clinical presentation. We report a case of primary mesenteric liposarcoma in a 55 year old man who underwent laparotomy for the clinical/radiological impression of a mesenteric cyst. FNAC was inconclusive due to suboptimal cellularity. On laparotomy there were 2 masses (diameter- 19 and 14 cms) weighing approximately 8.5 kilograms together. Histopathology showed features of atypical lipomatous tumor / well differentiated liposarcoma (ALT/WDLS) with mixed histological pattern (e.g. lipoma like, sclerosing and myxoid areas) varying from area to area. Prognosis of ALT/WD liposarcoma depends upon its anatomic location and most aggressive histological subtype. This case is being presented because of its huge dimensions, rarity of the site and mixed histological pattern.
