[Benign retroperitoneal schwannoma, laparoscopic ressection].

Schwannomas are tumors rarely localized in the retroperitoneum, generally appear in craneal as well as periferic nerves. Seldom cases the diagnosis is preoperatively made just because imaging is very poor in this field. MRI is proven to be the diagnostic method. Radical surgical ressection is standarized treatment. We document a case of a benign retroperitoneal schwannoma where we explain the laparoscopic ressection of this kind of tumors for first time.
