The ulcer measured approximately 2.5 cm in diameter, the border was irregular, raised and erythematous. The base of the ulcer was covered by a yellowish fibrinoid exudate. Figure 2 Histopathological examination showed inflammatory granulation tissue. Kinyoun stain revealed multiple acid-fast bacilli (arrows). Culture of tissue in Löwenstein-Jensen media yielded Mycobacterium tuberculosis. Intestinal tuberculosis should form part of differential diagnosis of patients presenting with lower gastrointestinal bleeding.
