Cutis. 2018 April;101(4):278-280

An otherwise healthy 29-year-old G2P1 woman at 32 weeks’ gestation presented to our emergency department with a 1-week history of a pruritic, burning rash that started on the thighs then spread diffusely. On physical examination, edematous pink plaques studded with 1- to 2-mm collarettes of scaling and sparse 1-mm pustules involving the arms, chest, abdomen, back, groin, buttocks, and legs were noted. The plaques on the back and inner thighs had a peripheral rim of desquamative scaling. There were pink macules on the palms, and superficial desquamation was noted on the lips. The oral mucosa was otherwise spared.
