[Generalized pustular psoriasis of pregnancy].

Pustular psoriasis of pregnancy is a rare entity. Clinically, it is characterized by an acute eruption of erythematous plaques studded with pustules during the third trimester. It may be localized or may spread to become generalized. The rash may be accompanied by constitutional symptoms and followed by complications such as sepsis, tetany secondary to hypocalcemia, placental insufficiency, and fetal morbidity and mortality. Therefore, early diagnosis and treatment are important. We present a case report of a patient who responded to corticosteroids and a review of the literature.
