Linearly distributed atrophic patches: a rare cutaneous manifestation of complex regional pain syndrome.

摘要

Complex regional pain syndrome (CRPS), a term comprising entities formerly known as reflex sympathetic dystrophy (RSD), causalgia and Sudeck's atrophy, is a severely painful and progressive disorder that usually develops after trauma. The major symptoms include pain [spontaneous pain, hyperalgesia, allodynia (pain evoked by nonpainful stimulus)], movement disorders, abnormal blood flow, sweating, and skin changes. Although cutaneous findings are an important clinical feature of CRPS, detailed reports on its skin alterations are few. We present a unique case of oval atrophic lesions with a linear distribution, a previously unreported type of skin manifestation in CRPS.
