Although less common, there are a few skin conditions related to pregnancy:

PUPPP (Pruritic Uticarial Papules and Plaques of Pregnancy) or Polymorphic Eruption of Pregnancy

This condition occurs in roughly 1% of pregnant women. It is characterized by itchy red bumps and hive-like rashes that usually appear on the belly or around stretch marks. The rash may spread to the arms, legs, breasts or buttocks. PUPPP usually begins in the third trimester of pregnancy. It is felt to be harmless to the mother and baby, but the itchiness can be severe. The cause up PUPPP is unknown. Treatment may the use of topical steroids, antihistamines and, in more severe cases, oral steroids to help alleviate the itching. PUPPP typical disappears after delivery.

Prurigo of Pregnancy (Prurigo gravidarum)

This is a rare condition characterized by itchy bumps on the shoulders and abdomen. It is often confused with scabies because of its appearance. It normally occurs in the 2nd half of pregnancy. The condition is felt to be harmless to mother and baby. Like PUPPP, it is generally treated with moisturizers or topical steroids if mild in severity or oral antihistamines if the itching is severe.

Pemphigold Gestationis (Herpes Gestationis)

This extremely rare condition auto-immune (body attacks the skin) starts as a hive-like rash, which then turns into blistering lesions. It usually begins on the abdomen and spreads to the mother’s arms and legs. Itching can be severe. It typically begins in the second or third trimester. Pemphigold gestationis may be associated with an increased risk for pre-term delivery and potential fetal harm. If you suspect you may have this condition, seek immediate medical attention.
