Abstract：A case of subacute cutaneous lupus erythematosus was reported.A 75-year-old female patient presented with scaly erythematous plaques and papules on her trunk and limbs,accompanied by flaky alopecia for over a year.Physical examination revealed widely scattered,erythematous plaques,approximately the size of a fingernail,on the head,face,trunk,and limbs.These plaques contained follicular papules and were covered with thin,light scales.Mild erythematous infiltration was noted on the scalp,with some lesions showing post-scratching blood oozing,crusting,and minimal scale shedding,without obvious exudation or tenderness.The patient was misdiagnosed as psoriasis vulgaris.Limited affection was observed with topical glucocorticoids and NB-UVB therapy.Dermatoscopic examination and histopathological analysis led to a final diagnosis of subacute cutaneous lupus erythematosus.The patient was treated with hydroxychloroquine sulfate 0.2 g twice daily,total glucosides of paeony 0.6 g three times daily,and prednisone acetate 30 mg once daily for 1 month.Topical halometasone cream was applied twice daily.Three months later,follow-up examination showed significant resolution of the scaly erythematous plaques on the trunk,with a small amount of pigmentation remaining,and new hair had grown in the areas of hair loss.
