Dental infection as a triggering factor in palmoplantar pustulosis

Abstract

Palmoplantar pustulosis (PPP) is a chronic disease characterized by sterile pustules on the palms and soles. Focal infections are closely associated with exacerbation of PPP, often accompanied by arthralgia. Tonsillitis is the most common culprit, whereas reports on dental infection are scarce (1). We describe here 4 cases of PPP in which dental infection is suggested to play a triggering role in the induction or deterioration of the disease. © 2013 Acta Dermato-Venereologica.
