Abstract
The gastrointestinal (GI) tract has been increasingly affected by tuberculosis, especially in immunocompromised patients. Although strict rectal involvement is rare, the GI site mostly affected is the ileocecal region. Thus, tuberculosis should always be considered in the differential diagnosis of perianal and rectal lesions, and more so in patients infected by the HIV virus. The authors report the case of a 32-year-old man presenting a long-term history of fever, night sweats, weight loss, bloody diarrhea, fecal incontinence, tenesmus, and rectal pain. HIV serology was positive. The patient underwent anoscopy and biopsy, which disclosed the diagnosis of rectal tuberculosis. Thus the patient was referred to an outpatient clinic to follow the standard treatment.
