[A rare cause of massive upper digestive hemorrhage. Duodenal tuberculosis, apropos of two cases].

Tuberculosis of the duodenum was revealed in two patients by severe upper digestive tract bleeding. These cases illustrate the difficulties in diagnosing tuberculosis of the duodenum which can present as a simple bleeding ulceration. This "infectious" ulcer is an exceptional finding but certain diagnosis can be made at laparotomy with extemporaneous pathology of the lymph nodes. For non-complicated cases, the diagnosis may be suspected on the bases of routine laboratory tests. Surgery should be limited as much as possible since specific antibiotics are usually successful in cases of digestive tract tuberculosis.
