[Polypoid eosinophilic cystitis mimicking bladder carcinoma].

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.
