A Possible Late Onset Variation of Papillon‐Lefèvre Syndrome: Report of 3 Cases

Abstract
Three unusual cases of papillon‐lefévre syndrome with late onset of features and relatively mild periodontal disease are presented. These examples confirm some of the late onset of features and mild periodontal presentation of a previous case report. Bacteriologic associations, polymorphonuclear leukocyte chemotactic, phagocytic, and bactericidal activity, and therapeutics with regard to this syndrome are discussed. J Periodontol 1993;64:379–386.
