permanent teeth.
Case Report: Both patients are male, born and living in Malayer, Iran. There is no history of similar disease in the parents, other siblings and maternal or paternal relatives.
Conclusions: Psoriasiform lesions accompanying palmoplantar keratoderma in patients should leading the physician to examine the mouth for premature loss of teeth and to ask the patient about the family history.
