Pustulosis palmoplantaris is a disease distinct from psoriasis

Abstract

Pustulosis palmoplantaris (PPP) is a chronic inflammatory skin disease with a considerable impairment of quality of life and is characterized by sterile pustules and red, scaly skin on the palms and soles. The position of PPP in relation to psoriasis is unclear. Some authors regard PPP as a distinct disease entity, whereas others categorize PPP as a manifestation of psoriasis. Related to this discussion is the question on the treatment of PPP. Should the treatment of PPP follow the guidelines for psoriasis or is it a disease that has to be treated in a different way? The purpose of this editorial is to review the differences between PPP and psoriasis and to understand these differences with respect to the pathogenesis and treatment.
