Neurogenic tumors of the brachial plexus

The Authors report two cases of solitary neurogenic tumors of the brachial plexus not associated with Von Recklinghausen's disease. Peripheral nerve tumors are relatively rare and only 25% occur above the clavicles. The mass, usually asymptomatic, may cause sensory radicular symptoms or rarely motor deficits in the involved arm. Wide radical excision of a benign neurogenic tumor is the treatment of choice; for malignant tumors, associated with a particularly poor prognosis, a more aggressive surgical approach may be necessary. Adjuvant radiation therapy and chemotherapy do not seem to have any effect on survival rates.
