Abstract
Haim-Munk and Papillon-Lefèvre are 2 closely related syndromes, inherited in an autosomal recessive pattern, manifested by palmoplantar keratoderma and early, destructive periodontitis. Recently, mutations in the cathepsin C gene have been recognized in both syndromes. We describe a patient with Haim-Munk syndrome (palmar plantar keratosis and periodontitis) and destructive arthritis of the wrists and shoulder joints, an association that has not been previously described.
