Figure 11. Mammary and chest wall tuberculosis and breast carcinoma in a 64-year-old woman. Mammogram of the left breast reveals a mass involving the posterior region of the breast secondary to chest wall tuberculosis. FNA cytologic analysis was performed (arrow indicates needle) and helped confirm that the mass was a result of chest wall tuberculosis. In addition, a small focus of architectural distortion was found in the outer quadrant (circle) that corresponded to an invasive ductal carcinoma. Square outlines a magnified view of the area of architectural distortion.
