Perforated appendicitis in a child with Henoch-Schönlein purpura.
Henoch-Schönlein purpura (HSP) is a common childhood vasculitis. Abdominal pain is a common feature of HSP, often leading to surgical consultation for evaluation of possible intussusception. Appendicitis is a rare complication of HSP, and in each of the 3 reported cases, appendectomy preceded the appearance of the purpuric rash. More often, unnecessary laparotomies are performed on patients in whom appendicitis is suspected, but who subsequently develop the characteristic purpura. This is the first reported case of appendicitis developing in a patient with the established HSP rash. This case is also the first report of perforated appendicitis in HSP. Clinical vigilance and serial physical and ultrasonographic examinations are needed to detect conditions necessitating surgery in patients with HSP.
