Granulomatous prostatitis diagnosed during intravesical BCG treatment

The bladder biopsy of 70-year-old man who had a bladder cancer diagnosis three years prior indicated a carcinoma in situ (CIS). Intravesical immunotherapy treatment was initiated. After severe dysuria symptoms, the immunotherapy treatment dosage was lowered. The treatment was then halted due to the progression of symptoms. A biopsy was performed due to prostate spesific antigen (PSA) and digital rectal examination abnormalities and 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 had been reduced, and his symptoms had regressed. The symptoms of severe dysuria, sterile pyuria, abnormal digital rectal examination and high PSA levels during intravesical BCG treatment led us to deduce a diagnosis of granulomatous prostatitis. This diagnosis was performed histopathologically, and the treatment of the patient proved successful.
