DISCOID LUPUS ERYTHEMATOSUS WITH PROMINANT OPEN COMEDO FORMATION: an unusual clinical presentation

Abstract

A 44-year-old male presented with inflammatory lesions, acneiform pitting scars with comedones on the right aspect of the nose for 5 years. Physical examination also revealed comedones on a mild erythematous base, atrophic scars and telangiectasia. Tracing back the history, there was no malar erythema, oral ulcer, or arthralgia. A skin biopsy showed large follicular pluging, perifollicular dense lymphocyte infiltration and marked melanin incontinence. He was successfully treated with 250mg/day chloroquine for 6 month. Two years later the patient were presented typical lesions for chronic cutaneous lupus lesions with comedo like lesions on the face and upper back. The laboratory tests were all normal. Cutaneous biopsy was characteristic of chronic lupus erythemathosus
