Long-term colchicine for recalcitrant palmoplantar pustulosis: treatment outcome in 3 patients.

Abstract

Palmoplantar pustulosis (PPP) is a chronic, relapsing, pustular eruption affecting the palms and soles for which treatment is often difficult and frustrating. Short-term colchicine has been used to treat PPP with variable response. We report on the successful treatment of 3 patients with severe, therapy-resistant, chronic PPP. We observed significant reduction in the frequency of pustular eruptions and the number of pustules with maximum tolerable doses of colchicine treatment for up to 12 months.
