Chilblain lupus erythematosus is an under-reported form of chronic CLE involving mainly the fingers and toes of smokers triggered by exposure to a moist cold environment. It may be familial with no association to SLE, or sporadic which can be associated with SLE.
Chronic cutaneous lupus erythematosus includes discoid lupus erythematosus, lupus erythematosus profundus, chilblain cutaneous lupus, and lupus tumidus.
Chilblain lupus erythematosus (CHLE) was first described in 1888 as cold-induced erythematous lesions before the terms ‘chilblains’ or ‘perniosis’ were coined. Diagnostic criteria exist for both chilblains and CHLE.
