Prurigo of pregnancy is a skin condition of pregnancy that results in itchy, small bumps on the arms, legs, and trunk.[3][4] These occur in small groups and scratching results in excoriation.[4][6] Onset is generally between week 20 and 34 of pregnancy.[5] It does not result in risks for the baby.[4][5]

The exact cause is unclear, but it likely a flare of eczema.[7][5] Risk factors are believed to include a prior history of eczema.[6] Diagnosis is generally based on symptoms and examination.[6] It is considered a diagnosis of exclusion.[8] It includes the conditions known as Besnier's prurigo gestationis, Nurse's early-onset form of prurigo, and Splangler's paupalar dermatosis of pregnancy.[6] It is type of atopic eruption of pregnancy (AEP), together with eczema in pregnancy and pruritic folliculitis of pregnancy.[9]

Treatment is with steroid cream.[5] Antihistamines may also help.[6] Other options may include benzoyl peroxide and UVB light.[8] Outcomes are good, with symptoms resolving within three months after pregnancy; though it may reoccur in future pregnancies.[6] Prurigo of pregnancy affects about 1 in 300 pregnant women.[4] It represents about 6% of rashes due to pregnancy.[6] The condition was named in 1904 by Ernest Henri Besnier.[6]
