title: [Multiple retroperitoneal neurofibroma. Report of a case].
abstract: Tumors of nervous origin in the retroperitoneum are rare without specific symptoms which diagnosis is usually very difficult. The authors report a case of an asymptomatic patient with two benign retroperitoneal neurofibromas, one of them calcified and located near the inferior pole of the left kidney; the other tumor was closely adhered to the pancreatic tail in the supramesocolic region. Both were resected with appropriated surgical margins. The histopathologic and immunohistochemical studies established the correct diagnosis of the lesions. The authors comment the diagnostic tests of these tumors, their possible malignant degeneration and their surgical treatment.
