Abstract：
:Eosinophilic cystitis (EC) is an uncommon inflammatory disorder of uncertain etiology that has been described in adult and pediatric populations. We describe 3 recent cases of EC that presented as a mass lesion in pediatric patients from the New England region of the United States. All patients were initially suspected to have a malignancy, and biopsy was performed, which ultimately led to the diagnosis of EC. We propose the use of eosinophil density of >25 eosinophils per high-power field and myocyte degeneration as supportive histopathologic features to make this diagnosis. It is of utmost importance to consider EC in the differential diagnosis when approaching a pediatric patient with a bladder mass.

UROLOGY文献大全abstract：:A wealth of clinical evidence supports the view that muscarinic receptor antagonists are effective in the treatment of overactive bladder. However, treatment-limiting adverse effects such as dry mouth, constipation, and blurred vision have restricted the usefulness of previously available agents, such as oxybutynin. A...
