Epithelioid
Epithelioid
Epithelioid (pronunciation: /ˌɛpɪˈθiːlɪɔɪd/) is a term used in pathology to describe the appearance of cells that resemble epithelial cells. The term is derived from the Greek words 'epi', meaning 'upon', and 'thelē', meaning 'nipple', referring to the nipple-like appearance of the cells.
Epithelioid cells are most commonly associated with granulomas, which are collections of immune cells that form in response to chronic inflammation or persistent infection. They can also be found in certain types of tumors, such as carcinomas and melanomas.
