Pruritic Urticarial Papules and Plaques of Pregnancy

Background
Pruritic urticarial papules and plaques of pregnancy (PUPPP) is a benign dermatosis that usually arises late in the third trimester of a first pregnancy.[1] The entity previously had been reported as toxemic rash of pregnancy,[2] toxemic erythema of pregnancy, and late-onset prurigo of pregnancy. The term polymorphic eruption of pregnancy (PEP) is used extensively in Great Britain, while PUPPP typically is used in the United States. Following atopic eruption of pregnancy, which occurs earlier in gestation, PUPPP is the second most common dermatoses of pregnancy.[3]
Epidemiology
Frequency
International
Pruritic urticarial papules and plaques of pregnancy (PUPPP) occur in 1 out of 160-240 initial pregnancies.
Mortality/Morbidity
No mortality is associated with pruritic urticarial papules and plaques of pregnancy (PUPPP). The mere appearance of an unusual skin eruption in pregnancy can provoke anxiety, but the pruritus is the most distressing feature. The latter weeks of pregnancy can be associated with many physical symptoms, and the severe itching of PUPPP may further debilitate and aggravate sleep loss in the weeks prior to delivery. No known systemic complications exist for affected females, and fetal mortality or morbidity do not increase.
Race
Pruritic urticarial papules and plaques of pregnancy (PUPPP) may be less common in blacks.
Sex
Pruritic urticarial papules and plaques of pregnancy (PUPPP) occur in females only.
Age
Pruritic urticarial papules and plaques of pregnancy (PUPPP) occur during childbearing years because it is a dermatosis related to pregnancy.
