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:IPLab1Tuberculosis8.jpg|This is a high-power photomicrograph of the Langhans-type multinucleated giant cell which is cells (arrows) that are characteristic of tuberculous granulomas (arrow). Note the horseshoe shape ring of the nuclei in this these giant cell. The majority of the cells in the upper left portion of this section are macrophages which provide the major cellular component in a granuloma. Note the smaller number of small blue-staining cells in the peripheral portions of this granuloma to the left of which are lymphocytes.
