Tuberculosis presenting as breast lump is a rare disease. This condition usually occurs in females who are in the reproductive age group. Diagnosis is quite difficult unless prompt investigations are meticulously done. They are often mistaken for malignancy. We report a 19-year-old girl with tubercular breast abscess. The abscess was incised and drained based on fine-needle aspiration cytology and ultrasonography revealed it as pyogenic abscess. Ziehl-Neelsen stain (ZN stain) of the pus sample showed acid-fast bacilli. Now, she has been started on antitubercular treatment.
