Abstract:
Eosinophilic cystitis is an inflammatory condition characterized by eosinophilic infiltration of whole layers of the bladder wall. The condition occurs more commonly in adults. We report a case of eosinophilic cystitis mimicking a bladder tumor in a 5-year-old boy with symptoms of dysuria and urinary incontinence. The diagnosis was confirmed by histopathology and he underwent clinical treatment with trimethoprim-sulfamethoxazole and antihistamine (cetirizine). The symptoms fully resolved in follow up, which is continuing. Although very rare, eosinophilic cystitis should be considered in cases of dysuria and increased bladder wall thickness but no identified urinary tract infection.
