Typiska celler vid granulomatös överkänslighet. De syns som stora, tillplattade celler med utökat endoplasmatiskt nätverk, och tros bestå av aktiverade makrofager som genomgått differentiering till följd av långvarig antigenstimulering. Ytterligare differentiering eller sammansmältning av epiteloida celler antas resultera i flerkärnade jätteceller.
Characteristic cells of granulomatous hypersensitivity. They appear as large, flattened cells with increased endoplasmic reticulum. They are believed to be activated macrophages that have differentiated as a result of prolonged antigenic stimulation. Further differentiation or fusion of epithelioid cells is thought to produce multinucleated giant cells (GIANT CELLS).
