[Hematuria, dysuria, pollakiuria and general malaise, in a patient treated with BCG instillations].

OBJECTIVE

To report a case of granulomatous cystitis in a patient receiving bacillus Calmette-Guerin intravesical therapy for urothelial carcinoma in situ.

METHODS

A 58-year-old man undergoing BCG intravesical therapy for urothelial carcinoma in situ presented symptoms of intense cystitis. Cystoscopy was performed and several bladder cold biopsies were obtained.

RESULTS

Histopathological analysis demonstrated epithelioid granulomas.

CONCLUSION

Cystitis arising from BCG therapy is defined as drug-induced or BCG-induced cystitis. Intense cystitis and malaise are a serious complication since it is not possible to distinguish patients with a simple uncomplicated local reaction from those who will develop progressive systemic infection. Cystoscopy and biopsy can be helpful in determining the nature of the condition and are recommended.
