Pustulosis palmaris et plantaris (PPP) is a rare and chronic inflammatory condition that primarily affects the palms of the hands and soles of the feet. Signs and symptoms of the condition generally develop during adulthood and include crops of pustules on one or both hands and/or feet that erupt repeatedly over time. Affected individuals may also experience itching (pruritus), pain, or a burning sensation. The classification of PPP is controversial. Some have proposed that PPP is a variant of psoriasis, while others believe it to be a separate disease. Though the area of involvement is often limited, PPP can have a significant effect on quality of life and can interfere with walking or other daily activities. PPP often has a chronic and relapsing course and may be resistant to treatment. Treatment options may include topical steroids, emollients, certain medications called retinoids, and treatment with light (phototherapy).
