A Case of Keratosis Follicularis Squamosa(Dohi)

Keratosis follicularis squamosa(Dohi) is an acquired keratinizing disorder, which is particularly common among Japanese and rarely reported in other countries. 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. We report a case of keratosis follicularis squamosa(Dohi) in a 39-year-old woman, who showed a clearance of the skin lesion after 4-week minocycline administration.
