What is meant by epitheloid secretory cells ?

Epithelioid cells are cells of the mononuclear phagocyte system found in certain granulomas mainly associated with the intense immuno logical activity. These cells show little phagocytic activity. In certain experimental granulomas such as those produced in guinea pigs sensitive to zirconium, and at sites of intense inflammatory reaction in man, they may contain varying amounts of rough endoplasmic reticulum (secretory epithelioid cells).
