Palmoplantar pustulosis (PPP) is a chronic pustular dermatosis of the palms and soles.
- PPP is more common in women, with a female-to-male ratio of 4:1.
- It's also associated with cigarette smoking, with up to 90% of patients identifying as smokers at the time of diagnosis.
- Average age 45
- An arthrosteitis has been associated and may be manifested by painful episodes of the anterior chest wall, and less commonly the knee, spine and ankle.
Deep-seated pustules on the palms or soles which don't rupture but instead turn brown is characteristic. The course is chronic.
Differential Diagnosis
Clinical examination should exclude the SAPHO syndrome which has this as a major skin manifestation. Ask for example, about swelling and sternoclavicular joint pain.
