Periodontitis is severe and destructive affecting both deciduous and permanent dentitions associated with palmo-plantar hyperkeratosis. These manifestations usually appear in childhood between 1 and 4 years of age and deciduous teeth exfoliate within or at the age of six. Permanent teeth erupt normally but soon get affected by periodontal disease. Individual becomes edentulous within teenage. Hyperkeratotic lesions extend to knees and elbows. Some cases have shown inconsistent manifestations such as calcification of falx cerebri and choroid plexus, calcification of the dura, attachment of the tentorium, thumb nail dystrophy and hyperhidrosis.
