Schwannoma of the Palmar Cutaneous Branch of the Median Nerve

Peripheral schwannomas are benign tumors originating from the Schwann cells of the peripheral nerve sheath. They make up a small percentage of the overall incidence of tumors of the hand, most commonly involving the ulnar nerve. The authors report a case of a 59-year-old patient with a slowly enlarging mass over his right wrist and no other symptoms. During surgery, a schwannoma involving the palmar cutaneous branch of the median nerve was found and successfully removed. This is a rare clinical entity, with few cases reported in the literature. In the current case, the lesion did not cause significant symptoms, and the authors demonstrated successful surgical enucleation of the lesion without complication.
