Pustular psoriasis of pregnancy (PPP), formerly known as impetigo herpetiformis is a form of severe generalised pustular psoriasis that occurs in pregnancy.[1][2] It typically presents in late pregnancy with a fever and generalised redness with pustules.[3][4]

Diagnosis is by signs and symptoms, and skin biopsy.[3] Blood tests typically reveal low calcium and high white cells.[3] Treatment may require corticosteroids by mouth.[2] It resolves following birth of the baby, but may recur in subsequent pregnancies.[2] PPP may harm the baby.[3]
