Clinical and epidemiological comparison of patients affected by palmoplantar plaque psoriasis and palmoplantar pustulosis: a case series study

Abstract

Our data suggest a close relationship between PPP and psoriasis. The existing data concerning epidemiology, clinical presentation, genetics, histopathology and pathogenesis do not permit a clear distinction between these two entities, which seem to coincide in many aspects. PPP appears to have a marked predilection among female smokers.
