Insights
Tuberculosis can rarely affect the epididymis following Bacillus Calmette-Guerin (BCG) therapy for bladder cancer. This case highlights a rare complication of BCG instillation, emphasizing the need for vigilance in diagnosing genitourinary tuberculosis.
Area of Science:
- Urology
- Oncology
- Infectious Diseases
Background:
- Bladder transitional cell carcinoma (TCC) is a common malignancy.
- Intravesical Bacillus Calmette-Guerin (BCG) is a standard immunotherapy for non-muscle invasive bladder cancer.
- Recurrence of bladder tumors necessitates treatment consideration.
Observation:
- A 72-year-old male with a history of bladder TCC underwent transurethral resection.
- Following intravesical BCG instillation for recurrent papillary tumors, the patient developed bilateral painful scrotal swelling.
- Symptoms persisted despite initial treatment with isoniazid (INH) and rifampicin (RFP).
Findings:
- Surgical intervention (right orchiectomy, left epididymectomy) revealed bilateral tuberculous epididymitis.
- Histopathological confirmation established tuberculosis as the cause of scrotal swelling.
- Post-operative anti-tuberculosis therapy led to symptom resolution.
Implications:
- Intravesical BCG therapy can, in rare instances, lead to genitourinary tuberculosis, specifically epididymitis.
- Clinicians should consider tuberculosis in the differential diagnosis of scrotal swelling after BCG instillation.
- Prompt diagnosis and appropriate anti-tuberculosis treatment are crucial for managing this BCG complication.
Abstract:
We describe a case of bilateral tuberculous epididymitis that occurred two weeks after intravesical Bacillus Calmette-Guerin (BCG) instillation. A 72-year-old man received transuretheral resection of bladder transitional cell carcinoma in November 2000. Although he had no recurrence for about 4 years, cystoscopy revealed small papillary tumors in the bladder in September 2004. A course of 8 weekly intravesical instillations of BCG was started. After the second BCG instillation (160 mg) he had bilateral painful scrotal swelling. Although he was administered isoniazid (INH) and rifampicin (RFP), scrotal swelling got worse. Right orchiectomy and left epididymectomy was performed in December 2004. Histological diagnosis was bilateral tuberculous epididymitis. Postoperatively, he was administered INH and RFP and had no recurrence for 3 months.
