Chilblain Lupus Erythematosus: A Case Report and Review of Literature / 대한피부과학회지

ABSTRACT

Chilblain lupus erythematosus (LE) is a rare, chronic form of cutaneous LE (CLE), which presents mostly in women as erythematous to violaceous plaques on the acral areas and face, precipitated by cold and damp climates. It may be accompanied by discoid LE (DLE) lesions or other forms of CLE. Up to 20% of patients develop systemic LE (SLE). Although two missense mutations in TREX1, encoding the 3'-5' repair exonuclease 1, were described in familial chilblain LE, the pathogenesis of sporadic chilblain LE remains unknown. To our knowledge, there are a few reports of chilblain LE in the Korean dermatologic literature. Herein, we present a rare and interesting case of sporadic chilblain LE in 71-year-old man and review the Korean literatures.
