[A case of reactivated tuberculous colitis after 9 months of anti-tuberculous therapy].

Tuberculous colitis, an important extra-pulmonary tuberculosis, is still prevalent in the developing countries and has been resurging in the Western world. The duration and dose of anti-tuberculous therapy have not yet been clarified in the tuberculous colitis. We experienced a case of tuberculous colitis, which relapsed after 9 months of therapy. A 28-year-old man presented with hematochezia and was diagnosed as tuberculous colitis on the basis of colonoscopic findings. He was treated with anti-tuberculous agents for 9 months successfully. Three months later, however, he complained of hematochezia again, suggesting the relapse of tuberculous colitis. He had taken anti-tuberculous therapy for another 15 months and showed no evidence of relapse. Although anti-tuberculous therapy is efficient for tuberculous colitis, rare cases of reactivation should be reminded.
