Our data confirm the benign, self-limiting nature of PEP and its favourable outcome for both the mother and the fetus. For the first time, we have documented a characteristic change in morphology with disease progression. The evidence of polymorphous clinical features in more than one-half of the patients favours the use of the term PEP. Multiple gestation pregnancies and excessive maternal weight gain, but not fetal weight and sex, were found to be significantly associated with PEP.

At the conclusion of this learning activity, participants should be aware of the main entities of the specific pregnancy dermatoses, their clinical presentations, the main diagnostic criteria and therapeutic options.
