Henoch-Schönlein purpura (HSP) is a systemic, generalized vasculitis of unknown etiology thought to be related to an IgA-mediated autoimmune phenomenon. Diagnosis is based on a constellation of physical findings that include the characteristic nonthrombocytopenic petechial or purpuric rash, migratory polyarthralgias, abdominal pain, and renal complications. We report the case of a 19-year-old man with a diagnosis of HSP who had severe abdominal pain and endoscopic documentation of duodenal involvement. Though not clear at presentation, the diagnosis became obvious when the characteristic rash emerged.
过敏性紫癜（HSP）是一种病因不明的全身性、广泛性血管炎，被认为与IgA介导的自身免疫现象有关。诊断基于一系列体格检查结果，包括特征性的非血小板减少性瘀点或紫癜皮疹、游走性多关节痛、腹痛和肾脏并发症。我们报告了一例19岁诊断为HSP的男性病例，该患者有严重腹痛，十二指肠受累的内镜检查记录。虽然在就诊时并不明确，但当特征性皮疹出现时诊断就变得明显了。
