Hemorrhagic Bullous IgA Vasculitis (Schönlein-Henoch purpura), Does it Have a Worse Prognosis?

Haemorrhagic bullous form of IgA vasculitis (IgAV), or Schönlein-Henoch purpura, is an unusual presentation of the disease in paediatric patients (<2%). Blistering eruptions can sometimes be very striking, leading to hospital admissions and administration of high-dose steroids and even immunosuppressants. Review of the literature, however, does not suggest that this clinical form carries a worse prognosis than the other forms of IgAV. In fact, the prognosis of the disease depends on the organic involvement. We present the case of a 5-year-old girl that is very representative. She developed palpable purpura and four days later the skin lesions evolved into blistering lesions. She did not receive any anti-inflammatory nor immunosuppressive treatment and the lesions spontaneously subsided within 14 days. She did not develop any extracutaneous nor systemic involvement.
