[Eosinophilic cystitis: review of nine cases].

BACKGROUND

Eosinophilic cystitis is a rare inflammatory pathology. It remains a poorly understood entity.

AIM

To report a series of adult cases of eosinophilic cystitis mimicking a bladder tumor.

METHODS

Retrospective study of cases of eosinophilic cystitis collected in an urology department.

RESULTS

Diagnosis was established on a spontaneous bladder perforation in one case and on hematuria in the eight other cases. Histopatholgy studies confirmed the diagnosis. Eight patients underwent an endoscopic resection of bladder lesions followed by medical therapy with nonsteroidal anti-inflammatory drugs and cortimoxazole. An ileal bladder enlargement was performed in one case. Regular follow-up didn't reveal any recurrence.

CONCLUSION

Eosinophilic cystitis is a rare disease simulating a tumor of bladder. Its clinical presentation is not specific and final diagnosis is based on pathology. Endoscopic resection will help to pathologic diagnosis. Associated to corticoids and antihistaminic drug endoscopic resection constitute the treatment of choice.
