Hyperkeratosis palmoplantaris (Papillon-Lefèvre syndrome). A case report.

A 16-year-old female presented with a severe chronic periodontitis and with associated hyperkeratotic lesions of her palms and soles. Investigations revealed it as a case of hyperkeratosis palmoplantaris (Papillon-Lefèvre syndrome), which is a rare form of an ectodermal dysplasia. Previously it was speculated that this disease entity is not all that uncommon in Nigeria especially amongst the rural population. However, recent investigations revealed that this is not correct.
