Henoch-Schönlein purpura (HSP) is the most common vasculitis in childhood and is clinically characterised by purpura, abdominal pain, arthritis and renal involvement. Scarcely, some patients with HSP may not always show visible rash and can present with insidious abdominal symptoms. We present two patients: an 8-year-old boy who was initially considered as having infectious diarrhoea and mesenteric lymphadenitis, then intussusception, appendicitis, appendicopathia oxyuriaca and post-operative ileus. However, he was finally diagnosed with HSP, as the typical rash appeared 10 days after onset of abdominal symptoms. The second patient was a 5-year-old boy with recurrent vomiting, abdominal pain and mild dehydration, where swollen joints and typical rash appeared on day 3. Both patients were successfully managed with orally administered corticosteroids. The patients did not have any further consequences of HSP.
