Are macrophages and histiocytes the same?

Histiocyte and dendritic cell lineages

DCs, monocytes, and macrophages are members of the mononuclear phagocyte system,² whereas a histiocyte is a morphological term referring to tissue-resident macrophages. Macrophages are large ovoid cells mainly involved in the clearance of apoptotic cells, debris, and pathogens.

Are histiocytes white blood cells?

Histiocyte cells are a form of white blood cells that help the immune system destroy foreign materials and fight infection. The extra immune cells produced by this condition may form tumors, which can affect parts of the body like the bones and possibly spread to other areas.
