Polymorphic eruption of pregnancy

Abstract

Polymorphic eruption of pregnancy (PEP) is a benign self-limiting dermatoses that occurs during pregnancy and/or the postpartum period. Etiology is unknown and evidence suggest a relationship between excessive maternal weight gain, cesarean deliveries, skin overdistension, multiple gestation and male fetuses. We present a case of PEP in a 26-year-old woman with twin pregnancy. We recommend prompt evaluation and diagnosis of a pregnant woman with primary skin lesions and pruritus to differentiate between the benign polymorphic eruption of pregnancy and other dermatosis which are associated with increased fetal morbidity.
