Gastrointestinal Tuberculosis Presenting as a Massive Lower Gastrointestinal Bleed in a Patient With Newly Diagnosed HIV/AIDS.

Gastrointestinal tuberculosis (GI TB) is an uncommon sequela of extrapulmonary TB, occurring in 1%-3% of TB cases worldwide. In the United States, many cases are seen in migrant populations or in immunocompromised individuals. The classic presentation of GI TB is nonspecific abdominal pain, and is not typically associated with significant, life-threatening bleeding. We present a case of GI TB complicated by severe lower GI bleed requiring vasopressor support in a newly emigrated patient with previously undiagnosed HIV/AIDS.
