Keratosis follicularis squamosa (Dohi) is a rare aquired keratinizing disorder, which is particularly common among Asians, including Japanese and Chinese. We report a case of keratosis follicularis squamosa (Dohi) in a 54-year-old woman, who had multiple dark brownish atrophic plaques with collarette scales on the buttock and thigh symmetrically. The biopsy specimen showed a dilated hair follicle with keratotic plugging and epidermal hyperkeratosis associated with slight parakeratosis. Gram positive cocci were demonstrated in the dilated hair follicle and horny layer. After 4 weeks of treatment with minocycline, the lesion showed a marked improvement.
