title: [Retroperitoneal tumors: a case of liposarcoma].
abstract: The Authors report a case of retroperitoneal sarcoma, in the histological subtype "liposarcoma", occasionally diagnosed in a 57 year old woman, who presented aspecific symptoms, characterized by dry cough, vomiting and chest pain. Chest TC showed a neoplasm of the retroperitoneum, close to liver, right colon, duodenum and right kidney. The arteriography of the right renal artery showed a neovascolarization inside the mass. A surgical resection was performed. The histological examination confirmed the diagnosis of liposarcoma. Liposarcomas account for 30% of the retroperitoneal soft tissue sarcomas; symptoms and diagnosis are late and the surgical resection of primary neoplasm, metastases and local recurrences representing the only therapeutic choice.
