This is a high-power photomicrograph of a granuloma. Note the necrotic core on the right (1), epithelioid macrophages (2), and Langhans’ type giant cells (3) at the periphery of the granuloma. Note also the small lymphocytes characterized by their distinctly blue-staining nuclei. Other cells in the tissue, in addition to the macrophages, include fibroblasts and occasional neutrophils.
