Eosinophilic Cystitis / 대한비뇨기과학회지

ABSTRACT

Since Brown first described the eosinophilic cystitis in 1959, 42 cases has been reported in the literature. In Korea, only 1 case was reported from the National Medical Center a couple of years ago. Eosinophilic cystitis is characterized histologically by infiltration of eosinophils into the mucosa, submucosa and muscularis of the bladder and cystoscopically by elevated erythematous mucosal lesions. These lesions have been mistakenly diagnosed as bladder tumors prior to biopsy. Clinically, it presents with dramatic and recurrent episodes of dysuria and hematuria. It can occur in two different clinical setups. The first is seen in women and children and is often associated with allergic disorders and eosinophilia. The second presents in older man and is usually associated with bladder injury related to other conditions of bladder and prostate. We herein add two cases of eosinophilic cystitis, review etiologic theories and outline management.
