[LYMPH NODE TUBERCULOSIS AFTER INTRAVESICAL BACILLUS CALMETTE-GUÉRIN THERAPY FOR BLADDER CARCINOMA IN SITU : A CASE REPORT].

A 66-year-old female patient received a total of six intravesical Bacillus Calmette-Guérin instillations as treatment for bladder carcinoma in situ. Six months later, she visited our hospital with a complaint of abdominal pain. Computed tomography revealed enlarged para-aortic and left common iliac lymph nodes. A laparoscopic retroperitoneal biopsy of the left common iliac lymph node was performed. Acid-fast bacteria culture of the resected specimen and a multiplex polymerase chain reaction assay showed lymph node tuberculosis. There was no evidence of Bacillus Calmette-Guérin infection. We administered four anti-tuberculosis drugs. After one year of treatment, the enlarged lymph nodes showed regression. This reduction in lymph node size was sustained for four years.
