We report a case of a 46-year-old female with pulmonary tuberculosis three years before, currently with stage C3 AIDS with a CD4+ lymphocytes count of 122. She attended the Hospital because of abdominal pain in the right lower abdominal quadrant, 4-5 liquid stools/day with dark blood, weight loss (7 kg), asthenia and anorexia in the last 3 months. Evening fever was reported in the previous 5 days. She was hemodynamically stable. There was no palpable adenopathy, but the presence of a tender mass in the right lower abdominal quadrant was noted. She had relative neutrophilia and CRP elevation (133 mg/L). CMV and EBV IgG antibodies were positive and IgM antibodies were negative. Abdomen ultrasound and Computed Tomography showed thickening of the terminal ileum and part of the ascending colon, with abnormal parietal enhancement, fat densification, a small area of focal wall necrosis and an adjacent adenopathy (Figs. 1 and 2). Both exams suggested tuberculosis and less probably lymphoma as possible diagnosis. Colonoscopy showed an ileocecal ulcerated neoformation (Figs. 3 and 4). Histology revealed diffuse B large cells NHL. It was an IIE/B stage with normal LDH and chemotherapy with cyclophosphamide, adriamycin, vincristine and prednisolone was started.

 

 

 

 

The gastrointestinal tract is the most common location of extra nodal NHL, associated with HIV. Lymphomas are late events during HIV infection, with the following associated risk factors: low CD4 + lymphocytes count, high viral load, advanced age, EBV infection and presence of AIDS-defining conditions.^2-4 It is important to equate this diagnosis in HIV positive patients with these features.
