Henoch-Schoenlein purpura (HSP) is a common vasculitic disorder of childhood. Patients with this disorder typically present with palpable purpura or petechia associated with one or more of the following signs and symptoms: abdominal pain, arthritis/arthralgias, and nephritis. The diagnosis may be difficult to make, however, when a patient presents with isolated symptoms such as abdominal pain without the typical rash. A high index of suspicion must be maintained to diagnose HSP in this setting and to avoid unnecessary interventions. This report describes two unusual patients with the presenting complaint of abdominal pain who had delayed onset of the purpuric rash, making the diagnosis of HSP difficult.
过敏性紫癜（HSP）是儿童常见的血管炎疾病。患有这种疾病的患者通常会出现可触及的紫癜或瘀点，并伴有以下一种或多种体征和症状：腹痛、关节炎/关节痛和肾炎。然而，当患者仅出现腹痛等孤立症状而无典型皮疹时，诊断可能会很困难。在这种情况下，必须保持高度怀疑指数以诊断HSP，并避免不必要的干预。本报告描述了两名以腹痛为主诉的不寻常患者，其紫癜皮疹出现延迟，使得HSP的诊断变得困难。
