We present 54 cases of tuberculosis (TBC) and Acquired Immunodeficiency Syndrome (AIDS) that were observed during five years and represent 37% of our AIDS patients. TBC was diagnosed before AIDS in 7, after AIDS in 5 and simultaneously in 42. Eighty-seven per cent were intravenous drug users (IVDU) and no hemophilia cases were recorded. The tuberculin skin test (PPD) showed a reaction greater than 5 mm in 43%. Prophylaxis has not been used in any patient. TBC was localized in 39% and disseminated in 61%; the lung was the main organ involved. Diagnosis was established by culture in 42 cases and by pathology exam in 12 cases. Eighteen patients had multiple isolations, while 36 had a single one. Co-occurrence with other opportunistic infections was observed in 27 cases. Death related to TBC was seen in 3 patients, and there were no differences in survival between disseminated and localized presentations. Compliance of treatment was very low and follow-up was not achieved in large number of patients.
