Tuberculous mastitis presenting as breast abscess.

Tuberculous mastitis is a rare clinical entity and usually affects women from the Indian sub-continent and Africa. It often mimics breast carcinoma and pyogenic breast abscess clinically and radiologically, may both co-exist. Routine laboratory investigations are not helpful in its diagnosis. Fine needle aspiration cytology (FNAC) / biopsy are essential for diagnosis and tuberculosis culture when positive may be very useful to guide antimicrobial therapy. Antitubercular drugs in combination with aspiration or surgical drainage are usually associated with an excellent outcome.
