Abstract
- Chilblain lupus erythematosus (LE) is a chronic unremitting form of LE seen predominantly in women. Chronic facial discoid LE frequently appears before the chilblain form. It may progress to systemic LE more frequently than other forms of chronic cutaneous LE do. We reported a case of chilblain LE in a 28-year-old male. He has had 1-5mm sized scaly erythematous macules on the ear, face, finger and toe tips for 10 years and these lesions have been aggravated in winter. Histopathologic findings were consistent with chilblain LE. The laboratory findings showed antinuclear antibody and anti-ds DNA antibody were positive but cryoglobulin and cold agglutinin were negative. One year later, lupus nephritis developed with leukopenia and decreased C3, C4 levels. He was diagnosed as systemic LE.
