Final answer:
Prurigo gravidarum is also known as Pruritic urticarial papules and plaques of pregnancy (PUPPP), diagnosed through clinical evaluation, and treated with antihistamines and topical steroids.
Step-by-step explanation:
The other name for prurigo gravidarum is Pruritic urticarial papules and plaques of pregnancy (PUPPP). The workup for PUPPP primarily involves a clinical evaluation, as this condition is typically diagnosed based on its characteristic appearance. In cases where the diagnosis is unclear, a skin biopsy can be performed. Treatment for PUPPP often includes antihistamines to reduce itching and topical steroids to reduce inflammation. It's important to note that although PUPPP is uncomfortable, it typically resolves after delivery and does not pose a risk to the fetus.
