Ischemic Neuropathy Associated with Livedoid Vasculitis

BACKGROUND Livedoid vasculitis is a chronic dermatological problem with an unclear etiology. Clinical findings are petechiae with painful ulcers in both lower extremities, which heal to become hyperpigmented and porcelain-white satellite lesions. There are only a few reported cases of livedoid vasculitis presenting in combination with peripheral neuropathy. CASE REPORT We report the first case of a Korean patient presenting with mononeuritis multiplex combined with livedoid vasculitis, which was confirmed by electrophysiological and pathological studies. CONCLUSIONS Our report supports the possible vaso-occlusive etiology of livedoid vasculitis in multifocal ischemic neuropathy.
