A case of generalized discoid lupus erythematosus: Successful treatment with Imiquimod cream 5%

Abstract

Discoid lupus erythematosus (DLE) is the most common form of chronic cutaneous lupus erythematosus. Classic DLE lesions begin as red-purple macules, papules, or small plaques and rapidly develop a hyperkeratotic surface. Most patients with untreated classic DLE lesions suffer indolent progression to large areas of cutaneous dystrophy and scarring alopecia that can be psychosocially devastating. A 44-year old male patient presented to the clinic with erythematous scaly patches that began on his nose 1 y before. His face was most affected, however, lesions were also noted on his scalp, ears, and limbs. Histopathologic examination verified a diagnosis of DLE. Laboratory examinations and consultations revealed no signs of systemic involvement. Imiquimod cream 5% was applied to the lesions once a day 3 times a week. After 20 applications, entire lesions regressed significantly. Imiquimod cream 5% may represent an alternative treatment method for patients with DLE.
