Pruritic urticarial papules and plaques of pregnancy. Involvement in mother and infant
A 19-year-old mother had pruritic urticarial papules and plaques of pregnancy. Similar eruptions were found on her newborn son. This recently recognized eruption of pregnancy, characterized by pruritic papules, papulovesicles, and urticarial plaques, has been seen previously only in mothers. The histologic findings are nonspecific and may include spongiosis, a lymphohistiocytic perivascular infiltrate, papillary edema, and occasional eosinophils. This report raises the possibility that infants may be affected.
