The occurrence of blistering eruptions in childhood Henoch-Schönlein syndrome has been so far addressed exclusively in individual case reports. To describe epidemiology, clinical presentation, and therapeutic options in Henoch-Schönlein patients ≤18 years of age with blistering eruptions, we completed a systematic literature search. For the final analysis, we retained 39 reports. Ten children with blisters were found in 7 (1.5%) case series containing a total of 666 unselected pediatric Henoch-Schönlein cases. We also found 41 individually documented cases of Henoch-Schönlein syndrome with blistering eruptions. Blistering eruptions and purpura were distributed very similarly, blisters developed concomitantly with palpable purpura or with a latency of ≤14 days, and 80% of the cases remitted within 4 weeks with a similar course in children managed expectantly and in those managed with steroids.
Conclusion: Blistering eruptions are rare in Henoch-Schönlein syndrome. They can be a source of diagnostic dilemma but do not have any prognostic value since they almost always spontaneously subside within 4 weeks.
What is known:
• Textbooks and reviews marginally refer to the occurrence of blistering eruptions in children with Henoch-Schönlein syndrome.

What is new
• Blistering eruptions occur in <2% of cases.
• Blisters and purpura are distributed similarly, blisters develop concomitantly with purpura or with a latency of ≤14 days.
• Almost all cases remit within 4 weeks with a similar course in children managed expectantly and in those managed with systemic steroids.
