Tuberculosis of the breast presenting as carcinoma.

Breast infections caused by Mycobacterium tuberculosis, although rare in western countries, should not be forgotten as a cause of a breast lump presenting clinically and radiologically as a carcinoma in the older patient who gives a history of previous tuberculosis. We report the case of an 84-year-old woman with a breast lump showing noncaseating granulomas on histology who developed a sinus track after excision biopsy of the lump. The patient responded to empiric treatment with anti-tuberculosis drugs and remains well 2 years after presentation.
