A Case of Keratosis Follicularis Squamosa (Dohi) Treated with Topical 1% Pimecrolimus / 대한피부과학회지

Keratosis follicularis squamosa (Dohi) is a keratinizing disorder which is a separate clinical entity from keratosis follicularis (Darier's disease). It occurs predominantly in Japanese and appears clinically as scaly patches of 3~10 mm in diameter with brownish follicular plugs in the center, which are symmetrically scattered on the trunks and thighs. Scales on the margin, slightly detached from the underlying epidermis, look like 'lotus leaves on the water'. The efficacy of minocycline has already been confirmed in many cases. In this report, we describe a case of using 1% of pimecrolimus cream for keratosis follicularis squamosa (Dohi) instead of minocycline.

It is characterized by multiple small brownish atrophic patches with follicular plug and collarette scales on the trunk and thighs . The scaly patches, which look like lotus leaves on the water as described by Dohi in the first report, is very characteristic.

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.
