Granulomatous prostatitis diagnosed during intravesical BCG treatment

The histopathological report of the biopsy material retrieved from hyperemic areas of the bladder during control cystoscopy of a 70-year-old man who had a bladder cancer diagnosis three years previously, indicated the presence of a carcinoma in situ (CIS). Intravesical immunotherapy treatment was initiated. After severe symptoms of dysuria emerging during intravesical immunotherapy with BCG, the immunotherapy treatment dosage was lowered. His treatment was then discontinued due to the progression of symptoms. A biopsy was performed due to higher prostate spesific antigen (PSA) and digital rectal examination abnormalities which indicated granulomatous prostatitis. An antituberculosis treatment was initiated because the PPD test result was 25 mm and the QuantiFERON test was positive. After one month, the patient’s PSA levels were reduced, and his clinical status improved. The symptoms of severe dysuria, sterile pyuria, abnormal digital rectal examination findings and high PSA levels during intravesical BCG treatment should remind us diagnosis of granulomatous prostatitis. It should not be forgotten that diagnosis of granulomatous prostatitis was established histopathologically, and the patient benefited from medical treatment.
