[Retroperitoneal tumor]

This paper presents the case of a 69 year old patient who has a benign retroperitoneal tumor (lipofibroma) presenting differential diagnosis problems (in special preoperative one, and intraoperative technique difficulties, revealing the fact that, in this case, paraclinical investigations have an orientative value, without offering etiologic information, and do not allow a clear preoperative strategy. Tumor resection was performed under an intraoperative histologically diagnosis of lipofibroma of the retroperitoneal region. Postoperative evolution was good.
