Abstract

Lipoma is a benign soft tissue tumor which rarely causes neuropathy. In closed compartments such as Guyon's canal, even small volume loss can lead to compression of nerve. Hence in such areas, even innocuous tumors such as lipomas can cause neuropathy and warrant surgery. We present one such case of ulnar neuropathy caused by lipoma of Guyon's canal.
