[Duodenal obstruction and upper gastrointestinal bleeding as the initial presentation of an isolated duodenal tuberculosis].

Primary duodenal tuberculosis is rare, even in endemic regions. The diagnosis poses a major challenge and requires a high index of suspicion, supported by imaging studies, microbiology, and histopatology obtained by endoscopic or surgical biopsy. We report the case of a 31-year-old man, without HIV infection or any previous history of tuberculosis, who presented with duodenal obstruction.
