Question

What is different between granulomas or epitheloid cells?

Answer 1

Histiocytes (specifically macrophages) are the cells that define a granuloma. They often, but not invariably, fuse to form multinucleated giant cells (Langhans giant cell). ... Epithelioid macrophages differ from ordinary macrophages in that they have elongated nuclei that often resemble the sole of a slipper or shoe.
