BACKGROUND Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. It has a characteristic rash described as palpable purpura that most frequently affects the distal lower extremities and buttocks. HSP rarely presents with bullous rash nor pulmonary nodules. CASE PRESENTATION We present a novel case of a 12-years-old female with recurrent pediatric HSP with a combination of the rare manifestations of bullous rash and pulmonary nodules. She initially presented with the bullous rash, chest pain, cough, and abdominal pain. Patient was successfully treated with intravenous pulse corticosteroids followed by a high dose oral corticosteroid taper, with resolution of the bullous rash and pulmonary nodules. CONCLUSION The rare manifestations of scarring bullous rash and pulmonary nodules can be presenting features of pediatric HSP, the combination of which has not been previously reported. The treatment of intravenous corticosteroid resolved patient's abdominal symptoms, rash and pulmonary nodules.

复发性过敏性紫癜伴大疱性皮疹和肺结节。

背景技术过敏性紫癜（HSP）是儿童最常见的血管炎。它具有被称为可触及的紫癜的特征性皮疹，该皮疹最常影响远端下肢和臀部。HSP很少出现大疱性皮疹或肺结节。病例介绍我们介绍了一名12岁女性伴小儿HSP复发的新病例，该病例合并了大疱性皮疹和肺结节的罕见表现。她最初表现为大疱性皮疹，胸痛，咳嗽和腹痛。患者已成功接受静脉内脉冲皮质类固醇治疗，随后口服大剂量皮质类固醇逐渐减少，并消除了大疱性皮疹和肺结节。结论瘢痕性大疱性皮疹和肺结节的罕见表现可能是儿科HSP的特征，之前尚未报告过其组合。静脉注射糖皮质激素可缓解患者的腹部症状，皮疹和肺结节。
