Papillon-Lefevre syndrome: a case report of four affected siblings

Four siblings, products of a consanguineous marriage, had palmoplantar keratoderma and loss of teeth. In addition, 3 of the siblings had psoriasiform plaques on their elbows and/or knees and 1 had intracranial calcifications. To our knowledge, this is the second largest reported number of affected members in a family with Papillon-Lefevre syndrome, a rare genodermatosis.
