Lateral antebrachial cutaneous neuropathy in a windsurfer.

Lateral antebrachial cutaneous neuropathy (LACN) was diagnosed in a young woman who developed pain and paresthesias in the right forearm after a long day of windsurfing (board sailing). The symptoms resolved with conservative treatment, including cessation of windsurfing and a brief course of oral corticosteroids. There was a permanent residual cutaneous sensory deficit in the distribution of the LACN. LACN is important to recognize because the symptomatology may mimic pathology of a cervical root, the brachial plexus, and the radial and median nerves at the level of the elbow.
