[en] Tuberculosis is still one of the leading cause of morbidity and mortality in developing countries. Patients with human immunodeficiency virus (HIV) tuberculosis infection can infect unusual sites and can have unusual presentations. Though tuberculosis can involve any part of the gastrointestinal tract, duodenal involvement is uncommon. Tuberculous lymphadenitis leading to a fistulous communication with duodenum is sparsely reported in literature. We here report a case of tubercular lymphadenitis eroding into the duodenal wall causing lymphadeno-duodenal fistula. (author)
