Carpal tunnel syndrome appearing with prominent skin symptoms.

A case of carpal tunnel syndrome (CTS) occurred in which the skin manifestations predominated over the neurologic symptoms. The skin changes included cyanosis, anhidrosis, alopecia, nail dystrophy, and episodes of acute necrosis. Carpal tunnel syndrome is the most common neuropathy accompanying nerve compression. The results of therapy depend on early diagnosis and the rapid relief from compression. Dermatologists should be well aware of this syndrome, which is almost entirely ignored in the major textbooks of dermatology.
