Abstract

We describe three patients with trophic ulceration and blistering of the fingertips associated with carpal tunnel syndrome. One of the patients also had non-insulin-dependent diabetes mellitus. Autonomic neuropathy distal to the carpal tunnel was probably present in all subjects at the time of presentation; in the patient with recent symptoms the skin was warm, and sweating was virtually absent, whilst the other two patients described cold skin, consistent with prolonged autonomic neuropathy.
