Diagnosis of GP becomes clear when skin lesions progress to tense blisters during the second or third trimester. The face and mucous membranes are usually spared. GP typically starts as a blistering rash in the navel area and then spreads over the entire body. It is sometimes accompanied by raised, hot, painful welts called plaques. After one to two weeks, large, tense blisters typically develop on the red plaques, containing clear or blood-stained fluid. GP creates a histamine response that causes extreme relentless itching (pruritus). GP is characterized by flaring and remission during the<unk>  and sometimes post partum period. Usually after delivery, lesions will heal within months, but may reoccur during menstruation.
