Abstract
In underdeveloped countries, Mycobacterium tuberculosis infection is common and typically manifests as pulmonary tuberculosis. Nevertheless, reports of tuberculous extrapulmonary involvement are also documented. Tuberculous breast abscess is a rare presentation, especially in immunocompetent hosts. Herein, a case of primary tuberculous breast abscess is presented. The patient came with complaints of pain in her right breast and a discharging sinus. A thorough diagnostic workup resulted in the establishment of a diagnosis with the detection of Mycobacterium tuberculosis on smear microscopy of pus, a cartridge-based nucleic acid amplification test, a line probe assay, and culture. Ultimately, she was put on anti-tubercular treatment.
