File:IPLab1Tuberculosis6.jpg|This photomicrograph shows a single nodule with an amorphous eosinophilic center and accumulations of cells around the outer edge. This is typical of a granuloma associated with tuberculosis in which there is a necrotic center (1) and a rim of lymphocytes, macrophages, and occasional multinucleated giant cells around the periphery.
File:IPLab1Tuberculosis7.jpg|This is a higher-power view of the granuloma with the amorphous eosinophilic material representing caseation necrosis (1), giant cells near the center (2), and inflammatory cells around the periphery.
File:IPLab1Tuberculosis8IPLab1Tuberculosis8b.jpg|This is a high-power photomicrograph of Langhans-type multinucleated giant cells (arrows) that are characteristic of tuberculous granulomas. Note the ring of the nuclei in these giant cells.
