Henoch-Schönlein purpura (HSP) is a small-vessel vasculitis mediated by IgA-immune complex deposition. It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura, abdominal pain, arthritis and renal involvement. The diagnosis of HSP is difficult, especially when abdominal symptoms precede cutaneous lesions. We report a rare case of paroxysmal drastic abdominal pain with gastrointestinal bleeding presented in HSP. The diagnosis was verified by renal damage and the occurrence of purpura.
过敏性紫癜（HSP）是一种由 IgA 免疫复合物沉积介导的小血管血管炎。其特征是临床四联征，即非血小板减少性可触及性紫癜、腹痛、关节炎和肾脏受累。HSP 的诊断困难，尤其是当腹部症状先于皮肤损伤出现时。我们报告了 HSP 中罕见的阵发性剧烈腹痛伴胃肠道出血的病例。诊断通过肾损伤和紫癜的发生得到证实。
