Digital schwannoma in a skeletally immature child

Soft tissue neoplasms of the hand are rare in general and even more uncommon in children. The most commonly considered diagnoses include ganglion, inclusion cyst, lipoma, subcutaneous foreign body granuloma, and tendon sheath xanthoma. Aside from pressure sensitivity, masses on the palmar aspect of the hand are often asymptomatic. The case reported here identifies a primary neural neoplasm (neurilemmoma) that involves a small peripheral nerve in the hand of a twelve-year-old child. The patient had no neurologic symptoms and illustrates the need to include neurilemmomas in the differential diagnosis of hand masses in children.
