Recurrent cystitis and bladder mass in two adults with chronic granulomatous disease.

Two men, aged 23 and 20 years, with recurrent episodes of severe cystitis and X-linked chronic granulomatous disease were studied. Ultrasonography showed large discrete bladder masses that mimicked bladder carcinoma in both patients. Urine and bladder biopsy cultures were negative and histopathologic findings were consistent with chronic inflammation. One patient improved with symptomatic therapy on two occasions; the other patient required prolonged intravenous antibiotic therapy before fever and dysuria resolved. The possible mechanisms by which such inflammatory bladder masses might arise are discussed and eight previously reported cases of chronic granulomatous disease with cystitis are reviewed. From this clinical experience, we recommend prolonged antibiotic therapy. In patients who fail to respond to antibiotic therapy, steroids may be cautiously administered.
