Rare disease: Benign palmar schwannoma – a rare case in a handball player

摘要

Peripheral nerve sheath tumours (PNSTs) of the hand are rare. Schwannomas, also known as neurilemmomas, are the commonest benign PNSTs. They arise from a proliferation of Schwann cells. Aetiology is unclear. In this report, the authors present the case of a lifelong Rugby Fives (a handball variant) player who developed a symptomatic benign schwannoma at the impact point on his palm. To our knowledge, there are no documented cases of upper limb schwannomas which may be related to repetitive trauma from sport.
