Scrofulous swelling of the bosom masquerading as cancer

Tuberculosis of breast is very rare with an incidence of 0.1-0.5%. It can be primary or secondary. Except in patients presenting with sinuses, it is a challenge to diagnose it. A 40 year old premenopausal lady presented with breast lump increasing in size for 3 months. Mammogram showed a lesion suspicious of malignancy and trucut biopsy showed necrotic material only. Intraoperatively there was caseous necrosis and the tract from breast was extending to rib. It is a rare case with few case reports been reported where a rib tuberculosis presents as a breast lump rather than retromammary abscess.
