The influence of histological classification on the options of the peripheral nerve tumors surgery Peripheral nerve sheath tumors (PNST) constitute significant part of all tumors of peripheral nerves. In 1998-2000 years we have operated 7 such patients--3 females, 4 males in our department. The definite diagnosis was made by histology. Total removal was performed in all patients. The nerve continuity was preserved in 4 cases (3x neurofibroma, 1x schwannoma) and nerve had to be disconnected in 3 cases (1x neurobibroma, 1x plexiform neurofibroma as a part of von Recklinghausen disease (VRD), 1x malignant schwannoma). Good neurological outcome was in patients with preserved nerve continuity. Out of 3 patients with the need of nerve disconnection, graft and complete reinervation was performed in case of benign neurofibroma, but in the patient with von Recklinghausen disease and in the patient with malignant schwannoma the permanent leasion of nerve remained. We can conclude that histological classification directly predetermine the options of the peripheral nerve tumors surgery.
