Keratosis lichenoides chronica (KLC) is a rare, acquired disorder of keratinization of unknown aetiology. The disease has a chronic and progressive course and is characterized by a poor response to almost all topical treatments and most systemic regimens. We report the first case of KLC in which there was a marked response in localized areas to photodynamic therapy (PDT) with methyl 5-aminolaevulinic acid (ALA).
