Neurothekeoma of the median nerve: case report.

We report the case of a large intraneural neurothekeoma of the median nerve at the wrist. Neurothekeomas are rare; they are small, superficial, and typically asymptomatic benign tumors of undetermined cellular origin. Complete excision is usually curative. This case is interesting owing to the tumor's large size and location within the median nerve, which made it highly symptomatic, mimicking carpal tunnel syndrome.
