title: [Retroperitoneal well-differentiated inflammatory liposarcoma].
abstract: Inflammatory liposarcoma represents a rare variant of well-differentiated liposarcoma in which a chronic inflammatory infiltrate predominates simulating the appearance of malignant lymphoma and other nonneoplastic lesions. A case of this lesion occurring in the retroperitoneum was described in 43-year-old man. The differential diagnosis, especially from lymphoma and non neoplastic lesions such as inflammatory myofibroblastic tumor and Castelman disease are discussed.
