[Schwannoma of brachial plexus: report of two cases]

Abstract

Schwannomas, neurinomas or neurilemmomas are benign peripheral nerve tumors. The literature report some cases associated with neurofibromatosis 2. We report two cases of cervical schwannoma originating from the brachial plexus unassociated with neurofibromatosis. A 31-year-old woman presented with a mass in the right supraclavicular region, irradiating pain and distal tingling to percussion (Tinel's sign) for 6 months. And a 52-year-old woman presented with pain in the cervical region and right arm for one year. Both the patients underwent to a microsurgery with total resection of the lesion. Histology of the surgical specimen confirmed the diagnosis of schwannoma. Postoperatively, the patients had a good recovery.
