Multiple neurilemomas in two patients show that these tumors may indeed be multiple, may involve the same nerve trunk, may occur over a period of years, and may involve different regions of the body. Twelve neurilemomas were removed from the right upper extremity of a patient over a 3-year period. They varied in size from 0.5 cm to 4 cm in diameter and had the typical histopathologic appearance of neurilemomas. The second patient had median nerve compression and at operation a neurilemoma was found compressing the nerve. Two years later, the patient had evidence of median nerve compression in the opposite extremity, and again a neurilemoma was found. Both of these patients had evidence of peripheral nerve compression, but the existence of multiple neurilemomas was not apparent on initial examination. These cases show that patients with neurilemomas may have additional sequential tumors discovered at a later date that were not apparent initially.
