A 65-year-old male had undergone transurethral resection of bladder tumor (TUR-Bt) four times for recurrent bladder cancer, and each histopathological examination revealed non-invasive urothelial carcinoma, pTa, G2. To prevent further recurrence, he received eight weekly intravesical instillations of Bacillus Calmette-Guérin (BCG). Four months after the BCG therapy, he underwent cystoscopy. One week after the cystoscopy, he developed a painful and swollen left scrotum. Treatment with levofloxacin for acute epididymitis reduced the scrotal pain initially, but the pain increased and 3 months later, a fistula with suppurative discharge appeared at the bottom of the scrotum. A smear of the discharge revealed Gaffky 2, and a culture showed tubercle bacillus. Incisional drainage of the abscess and anti-tuberculosis chemotherapy for 2 months to treat tuberculous epididymitis was not completely effective. We performed a left orchiectomy with resection of the infected scrotal skin. Histopathological examination showed tuberculous epididymitis consisting of a caseating granuloma with epithelioid cells and Langhans giant cells. He received anti-tuberculosis chemotherapy for 4 months postoperatively and had no sign of recurrence 1 year postoperatively.
