A Mutation in Cathepsin C Gene Causing Papillon-Lefevre Syndrome in a Saudi Patient: A Case Report.

ABSTRACT: Papillon-Lefèvre syndrome (PLS) is a rare genetic disease that causes dermatological and dental symptoms that usually start from early age. Dermatological findings include hyperkeratoderma over the palms and soles that are usually thought of as persistent psoriasis at first. Dental findings include severe caries in the teeth that lead to premature dental loss. We present a case of an otherwise healthy seven-year-old child with classical presentation of PLS with both dermatological and dental findings. He first presented to the dermatology clinic when he was five years old brought by his parents complaining of dry scaly patches on the palm of the hands and soles of the feet. On further history it was found that he is a child of first-degree consanguinity, and he had these patches since he was four months old. On examination, he was found to have an erythematous hyperkeratotic skin plaques and papules with scales over the planter and palmar aspect of both hands with similar lesions observed on both feet, legs, scalp, and ears with nail pitting. The diagnosis of PLS was confirmed by whole-exome sequencing (WES) and the patient was started on acitretin capsules and started to show improvement.
