The specific dermatoses of pregnancy are rare and consist of pemphigoid gestationis (PG), intrahepatic cholestasis of pregnancy (ICP), polymorphic eruption of pregnancy and atopic eruption of pregnancy. The dermatoses are characterized by pruritus, and they are important to recognize since PG and ICP increase the risk of prematurity, fetal distress and stillbirth. Diagnosis is based on medical history, morphology, blood sample and biopsy. The dermatoses are treated with respectively ursodeoxycholic acid (in case of ICP) and steroids. Breast-feeding is recommended and induction of labour is not normally indicated.
