Churg-Strauss syndrome revealed by acute abdominal pain.

We describe a 10-year-old girl with Churg-Strauss syndrome, who presented with acute abdominal pain, bloody diarrhea, and pulmonary infiltrates. She had a 6-year history of severe asthma. Bronchoalveolar lavage showed marked eosinophilia. She responded well to high-dose intravenous corticosteroid pulse therapy for 3 consecutive days, followed by oral steroids without developing major side effects. This case should remind pediatricians of the rare existence of this vasculitis in children. Relapse is not uncommon, and long-term careful supervision is necessary.
