EPITHELIOID CELL Meaning and
Definition
-
Epithelioid cells are a type of cell that resemble epithelial cells in their appearance and function. Epithelial cells are the building blocks of epithelial tissues, which line the surfaces and cavities of organs and structures in the body. These cells typically have a distinct morphology and form tightly-packed sheets, providing a protective barrier lining.
Epithelioid cells are characterized by their round to polygonal shape and contain a large, centrally located nucleus. They often have a prominent nucleolus, which is responsible for the production of ribosomes and plays a key role in protein synthesis.
These cells can be found in various tissues and organs throughout the body and are involved in a multitude of physiological processes. Epithelioid cells are particularly prominent in tissues involved in immune responses and inflammation, such as granulomas. Granulomas are organized collections of epithelioid cells that form in response to chronic infections or immune-mediated diseases.
The presence of epithelioid cells can be indicative of certain diseases and conditions. For example, the presence of epithelioid cells in lung tissue may suggest granulomatous lung diseases, such as tuberculosis or sarcoidosis. In addition, the appearance of epithelioid cells in certain cancers, such as epithelioid sarcoma, can aid in diagnosis and treatment planning.
Overall, epithelioid cells play an essential role in the body's defense mechanisms and provide valuable diagnostic clues for various diseases and conditions.

Etymology of EPITHELIOID CELL
The word "epithelioid" comes from two separate components: "epithelium" and "-oid".
"Epithelium" is derived from the Greek word "epi", meaning "upon" or "on", and "thēlē", meaning "nipple" or "teat". It refers to the thin layer of cells that covers the surfaces of organs, glands, and cavities of the body.
The suffix "-oid" is also derived from Greek and means "resembling" or "having the shape of".
Therefore, an "epithelioid cell" is a cell that resembles or has the shape of epithelial cells, which are typically found in the epithelium. Epithelioid cells are commonly seen in certain types of tumors and inflammatory conditions.
