OBG · Complications of pregnancy: PUPPP
Sample itemA primigravida at 35 weeks has intense itching with erythematous urticarial papules that began within her abdominal striae and spare the periumbilical skin. There are no blisters, and immunofluorescence of a skin biopsy is negative. What is the most appropriate management?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Topical steroids, antihistamines and reassurance
Polymorphic eruption of pregnancy (PUPPP) typically starts in abdominal striae of a primigravida in the third trimester and spares the umbilicus. It is self-limiting, carries no fetal risk, and is treated symptomatically with emollients, topical steroids and antihistamines. Pemphigoid gestationis typically starts around the umbilicus with blisters and has positive immunofluorescence.
Option by option
A. Ursodeoxycholic acid for presumed cholestasis
Cholestasis presents with itching without a rash, and the rash here is primary.
B. Early delivery by induction of labour
Delivery is not needed as the condition resolves after birth and does not harm the fetus.
C. Oral prednisolone for presumed pemphigoid gestationis
Pemphigoid gestationis has periumbilical blisters and linear C3 on immunofluorescence, which are absent here.
D. Topical steroids, antihistamines and reassurance (correct)
Correct. This benign condition needs symptomatic treatment only and has no adverse fetal effects.
