A large palmar lipoma arising from flexor tenosynovium of the hand causing digital nerve compression: A case report

Abstract

Lipoma is a common benign soft tissue tumor which rarely occurs in the hand. Lipomas of the hand seldomly cause pain or other symptoms. However, in certain areas, the mass effect from the lipoma may cause clinical symptoms. It rarely involves the deep areas such as synovial membrane and muscle and, sometimes, pressure on the peripheral nerves can cause pain and neurological symptoms. The treatment is surgical resection with a low rate of recurrence. However, the rate of recurrence is high in deep and infiltrating lipomas which preclude complete resection. In this article, we report a case of a large palmar lipoma arising from the flexor tenosynovium of the hand causing digital nerve compression.
