Púrpura Henoch-Schönlein bullosa en pediatría. Reporte de caso

Introduction: Henoch Schonlein purpura (HSP) is the most common type of vasculitis in childhood. HSP affects small blood vessels, and it rarely leads to serious complications such as bullous small vessel vasculitis, as it occurred in the case presented here. Case presentation: 5-year-old male who was brought to a primary healthcare center due to having arthralgia and purple skin lesions on his lower limbs. After the patient was diagnosed with HSP, he developed bullous lesions, so he was hospitalized and analgesic and topical management was started. During his hospital stay, the patient’s renal function was monitored, and since he did not experience other complications, he was discharged. Conclusion: The available literature on HSP suggests that its cutaneous bullous manifestation rarely occurs in pediatric population and that, unlike normal HSP cases, it is not always associated with renal and/or gastrointestinal involvement. However, regardless of the dermatological severity of this type of vasculitis, the function of the gastrointestinal and renal systems must be always monitored in these patients.
