OBJECTIVE: To report an additional case of polypoid eosinophilic cystitis mimicking a urothelial carcinoma of the urinary bladder. METHODS: An 81-year-old man presented with hematuria and dysuria that he had noted for the past month. The US findings were consistent with a bladder tumor and consequently the patient was submitted to transurethral resection. RESULTS: Histological analysis disclosed inflammatory infiltrates with numerous eosinophils (eosinophilic cystitis), but no evidence of tumor. The patient is well two years later. CONCLUSIONS: The present case demonstrates that polypoid eosinophilic cystitis can mimick a bladder carcinoma. Histopathological analysis is necessary for the differential diagnosis.
