[Primary tuberculosis of the breast: a case report]

Tuberculosis of the breast is an uncommon disease. The authors present a case of an asymptomatic 64 year-old patient whose mammography showed a right breast nodule which needed aetiological investigation. Complementary diagnostic exams did not lead to a differential diagnosis between granulomatous lesion and breast carcinoma; nodule aspiration results suggested tuberculosis of the breast but were unclear and so tuberculosis antibiotics were initiated. No other tuberculosis infectious focus was found at clinical- laboratory evaluation. Imagiology progress was favourable, so patient continued treatment. The authors highlight the low rate of primary tuberculosis of the breast and make a brief reference to the pathology, which has a low rate of microbiological and pathological- anatomical identification.
