A case of pustular psoriasis of pregnancy with positive maternal-fetal outcomes.

Pustular psoriasis of pregnancy (PPP), also known as impetigo herpetiformis, is a rare condition that affects women in the third trimester of pregnancy through the postpartum period. The relative infrequency of PPP presents both clinical and pathologic challenges in the diagnosis and management of this condition. We report a case of a woman who presented at 32 weeks' gestation with a generalized rash demonstrating clinicopathologic features consistent with PPP. Based on prior reports of adverse maternal-fetal outcomes in PPP, coordinated efforts from our patient's dermatologic and obstetric teams ensured positive outcomes for the patient and the neonate.
