Eosinophilic granulomatous cystitis in children

We report 3 cases of eosinophilic granulomatous cystitis in children. All presented with hematuria, urinary urgency, and dysuria. Treatment with oral corticosteroids led to rapid and complete recovery in 2 of the 3 cases. In the third case recovery was prolonged without the use of steroids. Because of the presumed immunologic nature of this disease, previous authors have recommended the use of corticosteroids in its management. A review of the literature suggests that the disease is probably of immunologic nature and that corticosteroids shorten symptomatic recovery from this disease.
