Successful Treatment of Darier’s Disease with Adapalene Gel

Abstract: We report a 12‐year‐old Japanese boy with a 3‐year history of skin lesions that had been unsuccessfully treated with topical steroids. We initiated two different topical treatments with adapalene gel 0.1% (Differin^® Gel 0.1%) and high‐concentration vitamin D3 (tacalcitol) ointment; the lesions treated with adapalene gel improved dramatically in the first 2 months, whereas the high‐concentration vitamin D3 ointment resulted in little improvement. Topical adapalene gel 0.1% may be a promising choice as a topical treatment of Darier’s disease because of its high efficiency and lack of adverse effects.
