Breast tuberculosis is a rare form of tuberculosis. Of all the breast diseases treated surgically, tuberculosis is seen in the range between 0.025% and 0.1%. This ratio is higher in undeveloped countries. We presented five cases with breast tuberculosis. Their ages were between 20 and 63 years. All of them had children and were breastfeeding. The cause of admission to the hospital was swelling in four of them and pain in the remainder. All of the lesions were unilateral. One case had received antituberculosis treatment for pulmonary tuberculosis 10 years ago. AAFB was not detected in sputum, breast discharge, urine and tissue culture in all the cases. Diagnosis was made histopathologically from the excisional biopsy material. Caseating granulomatosis was also found in axillary lymph nodes in three cases. Antituberculosis therapy was planned as 2HRZE/4HR for all of the cases. Three of them completed the therapy without any complaints. One case left the hospital without permission. The last one is now undergoing resistant tuberculosis treatment for pulmonary disease without any complaint of her breast. As a conclusion, although tuberculosis of breast is extremely rare, it should be kept in mind particularly in developing and undeveloped countries.

Primary pulmonary lymphomas (PPL) only constitute 4% of extra-nodal, non-Hodgkin lymphomas (NHL), less than 1% of NHL in general, and between 0.5% and 1% of malignant pulmonary neoplasms. Fifty-eight to 87% of cases of this extremely uncommon disease are low-grade B-cell lymphomas and 11%-19% are high-grade or large B-cell lymphomas. The prognosis for.high-grade or large B-cell lymphomas is worse than for low-grade lymphomas; respiratory and general symptoms are usually present. However asthmatic symptoms are not often found in their clinic. We report the case of a 49-year old woman with resistant asthma clinic in the form of wheezing, dyspnea and non-productive painless cough; associated with an irregular lobulated mass with air bronchograms in the lower lobe of the right lung. Histological diagnosis showed a pattern of high-grade B-cell lymphoma and all asthmatic symptoms disappeared following gross total resection of this lesion.

Pulmonary involvement is one of the most common extra-articular manifestations of rheumatoid arthritis (RA). We studied four smear-positivepulmonary tuberculosis patients who had had RA for 2.5-12 years. Three of them were using corticosteroids at the time of diagnosis. The clinical, radiological and bacteriological features of all the patients were examined. We conclude that when patients with RA have symptoms related to pulmonary involvement, tuberculosis should be considered, particularly in developing countries.
