PUPPP stands for pruritic urticarial papules and plaques of pregnancy. Also known as polymorphic eruption of pregnancy (PEP), it is one of the most common types of rash you can get during pregnancy.

Herpes gestationis (HG) Abdominal urticarial lesions may be clinically indistinguishable from the lesions seen in women who have PUPP, though in HG, bullae and larger vesicles are common.
