Abstract:

A case of ulerythema ophryogenes （UO） is reported. A 12-year-old boy presented with erythema and follicular papules on the eyebrows and cheeks for 7 years. The lesions started as follicular papules surrounded by erythema, then spread symmetrically to the cheeks and forehead followed by the loss of eyebrows. There was no complaint of pruritus. Physical examination showed pinhead- to grain-sized, smooth, slightly indurated follicular hyperkeratotic papules surrounded by erythematous halo on the eyebrows, forehead and cheeks. Both eyebrows were nearly completely lost. Histological analysis of lesions from eyebrows revealed dilated follicular infundibulum with orthokeratotic plugs, sparse perivascular and perifollicular lymphohistiocytic infiltrate, widened and sclerotic collagen fibers in the dermis. According to the clinical manifestations and histopathological findings, the patient was diagnosed with ulerythema ophryogenes, and given oral vitamin A 2.5 million unit once a day, vitamin E 100 mg once a day, topical vitamine E cream twice a day, 0.025% tretinoin ointment once at night. Two weeks later, the lesions improved.
