[A case of male who was taken systemic lupus erythematosus with chilblain lupus].

A 38-year-old male was admitted to our hospital because of high grade fever, erythema of face and extremities and oral ulcer. The laboratory examination showed leukopenia, high titer (320 dil.) of antinuclear antibody, a positive reaction of anti-Sm antibody. Especially histopathology of hand erythema showed hydrophilic degeneration consist with chilblain lupus. Because his symptoms were consistent with the criteria of American College of Rheumatology (1982), he was diagnosed as systemic lupus erythematosus (SLE). After administration of 60 mg prednisolone daily, the symptoms gradually improved. Any recrudescence of serological abnormalities or clinical symptoms was not observed until now, although chilblain lupus still persisted. Originally SLE is frequent in young female and often attended with renal disease, central nerve disease and serositis. We reported a case of middle-aged male who developed SLE with chilblain lupus which was rare skin lesion of SLE without severe organic lesion and discussed the relation among chilblain lupus, discoid lupus erythematosus (DLE) and SLE.
