Abstract
Schwannomas, arising from Schwann cells of a nerve sheath, are the most common benign tumors of the peripheral nerves. Schwannoma cause symptoms including paresthesia and motor weakness depending on involved nerves or pain after growing enough to compress surrounding soft tissue. Here in this case, schwannoma was originated from the median nerve at the mid humerus, but the tumor did not cause median neuropathic symptom but ulnar neuropathic symptom by compressing the ulnar nerve.
