Quote from Robbin's pathology with citation


In the usual H&E stained tissue samples (Fig. 3.22), the activated macrophages in granulomas have pink granular cytoplasm with indistinct cell boundaries and are called epithelioid cells. A collar of lymphocytes surrounds the aggregates of epithelioid macrophages. Older granulomas may have a rim of fibroblasts and connective tissue. Frequently, but not invariably, multinucleated giant cells 40 to 50 µm in diameter are found in granulomas; these are called Langhans giant cells. They consist of a large mass of cytoplasm and many nuclei.
