Successful treatment of pityriasis lichenoides chronica with narrow-band ultraviolet B therapy in a patient with Keratitis-Ichthyosis-Deafness syndrome: a case report.

Keratitis-ichthyosis-deafness (KID) syndrome is a rare genodermatosis causing ichthyosis-like skin lesions, keratitis, and deafness. Herein, we report a patient with this rare syndrome in association with pityriasis lichenoides chronica, which was succesfully treated with narrow-band ultraviolet B phototherapy despite our concerns regarding the increased risk of squamous cell carcinoma, hyperpyrexia, and keratitis.
