Tuberculosis (TBC) is a major public health problem with high mortality especially in developing countries. It is associated with a higher risk of developing pulmonary and non-pulmonary malignancies including solid and hematologic cancers. Association between TBC and nonpulmonary malignancies is rarely described in the literature. To describe the epidemiological, clinical, therapeutic modalities and the evolutive aspects of patients treated for cancer and TBC. This is a retrospective study conducted over a period of 19 years (between 1993 and 2012), including 10 patients followed up for cancer and tuberculosis at the department of oncology and the department of infectious disease, CHU Habib Bourguiba Hospital and CHU HediChaker, Sfax, Tunisia. The average age of patients was 55 years old. The sex ratio was 1. The different locations of cancer were represented by the breast (4 cases), the nasopharynx (1 case), the colon (1 case), the kidney (1 case) the gum (1 case), the endometrium (1 case) and the blood (1 case).TBC and cancer were synchronous in 5 cases. Concerning the metachronous presentation that interested 5 patients, the average time betweenthe onset of TBC after cancer diagnosis was 3.5 years. Three of these patients were treated by chemotherapy with radiation therapy. TBClocalization was nodal in 6 cases, spinal one case, nasopharyngeal in one case, peritoneal in one case and urogenital in one case. The diagnosisof TBC was made incidentally in two cases during axillary lymph node dissection. The therapeutic management of cancer was based on surgery,chemotherapy and / or radiotherapy. All patients received anti TBC treatment for at least six months. Surgery was indicated in one case(laminectomy). A complete remission of cancer was observed in 9 patients. Concerning TBC, recovery was observed in 8 patients, 1 patient hada spinal recurrence and 1 patient is being treated. Chronic inflammation during TBC can lead to cancer development. The etiopathogenesis of this association is still imperfectly known. Association between TBC and non-pulmonary cancer, although rare, should be always kept in mind in order to handle in time these two diseases in order provide the best chances of recovery for patients.
