We describe a 7-year-old boy with Churg Strauss syndrome who presented
with a 3-month history of cough, wheeze, fever, weight loss, abdomina
l pain, skin lesions, proteinuria and pulmonary infiltrates with eosin
ophilia. He showed a good response to corticosteroid treatment and is
currently doing well. The case illustrates the difficulty and importan
ce of reaching a diagnosis in a rare condition for which there is an e
ffective treatment, and serves to remind paediatricians of its existen
ce.
