title: Inflammatory variant of a well-differentiated retroperitoneal liposarcoma: case report of a rare giant variety.
abstract: Inflammatory liposarcoma is a rare variant of a well-differentiated liposarcoma (WDLPS). We present a case of a 37 years old male who had a giant variety of this inflammatory WDLPS. CT scan revealed a large abdomino-pelvic mass abutting the left kidney and pushing the IVC, Aorta and the left ureter across the midline. CT guided FNAC did not reveal any malignant cells. A large 9-kg fibro-fatty mass, which appeared irregular, congested and bosillated was excised. Microscopic picture revealed foci of fibrosis with mature adipose tissue. Lymphocyte and plasma cell infiltrate was abundant along with multi-nucleate giant cells and few lipoblasts. There are no case reports of a giant inflammatory variant of WD-LPS in world literature and this is the first of its kind from the Indian sub-continent. We present a case report of this rare giant variant of inflammatory WDLPS and discuss the review of literature.
