| Abstract: | Both metal allergy and dental focal infection have been considered as causative factors for palmoplantar pustulosis, and several case reports described that the skin lesions were ameliorated after dental metal removal or dental infection control. However, limited data are available to evaluate the association of these factors with disease severity of palmoplantar pustulosis. This study is designed to analyze the clinical outcome of 85 palmoplantar pustulosis patients after dental infection control (n = 70), tonsillectomy (n = 6) and dental metal removal (n = 9). More than half of the patients (63%, 44/70) showed positive clinical outcome after dental infection control. The skin lesions of all patients with tonsillitis were improved after tonsillectomy (100%, 6/6). On the other hand, one‐third of patients (33%, 3/9) showed positive response after dental metal removal. These results suggest that focal infection is more closely associated with palmoplantar pustulosis than dental metal allergy. According to our findings, palmoplantar pustulosis patients should be preferentially examined for focal infections. |
