A Case of Eosinophilic Cystitis / 대한비뇨기과학회지

ABSTRACT

Eosinophilic cystitis is a rare inflammatory disease of bladder with unknown etiology. The disease is known to be associated with several different processes such as allergy or injury. Eosinophilic cystitis is similar to interstitial cystitis, tuberculosis and bladder neoplasms in the clinical manifestations and should be differentiated from them. A 42-year-old male patient presented with gross hematuria, frequency and dysuria. Urinalysis showed hematopyuria. Cystoscopy revealed a hemorrhagic and necrotic polypoid mass, measuring 3cm in diameter on the dome of the bladder. Pathology of the lesion revealed the diffuse eosinophilic infiltration of the bladder wall without evidence of malignancy. The patient was treated with a 2-month course of 10mg prednisolone 3 times a day. The symptoms improved. After 3 months, followup cystoscopy and cystography showed normal findings.
