Diagnosis and Management of Papillon-Lefevre Syndrome: A Rare Case Report and a Brief Review of Literature.

Papillon-Lefevre syndrome (PLS) manifests as an autosomal recessive disorder caused by a mutation in the cathepsin C (CTSC) gene. This genetic alteration results in palmoplantar hyperkeratosis, rapid onset of periodontitis, and premature shedding of both primary and permanent teeth. The major etiological factor responsible for the development of this disorder appears to be variations in the CTSC gene, which is responsible for the production of the cathepsin C enzyme in the body. The multifactorial aetiology of the syndrome is influenced by immunologic, genetic, or microbial factors. This case report presents a clinical picture of a 21-year-old Indian male patient with oligodontia and mobile teeth accompanied by palmoplantar keratosis and a history of recurrent infection. The detailed family history of the patient revealed genetic relevance with PLS. This article will discuss in detail the diagnosis, evaluation and treatment modalities involved in the management of the case.
