What does sarcoid mean?
A sarcoid is a benign, granulomatous lesion or mass most often encountered in discussions of sarcoidosis, a systemic inflammatory condition that can affect the lungs, lymph nodes, skin, eyes, and other organs. The adjective sarcoid describes tissue or a reaction resembling that associated with sarcoidosis. In medical use, “sarcoid granuloma” commonly refers to a granuloma made up largely of epithelioid cells and giant cells, often without central caseous necrosis. Although the word can sound like a tumor name, it does not ordinarily denote a malignant growth such as a sarcoma. The term is mainly used by clinicians, pathologists, and researchers rather than in general conversation, so readers may encounter it in diagnostic reports and specialist literature.
A benign granulomatous lesion or mass, especially one associated with sarcoidosis.
"The scan identified a small sarcoid in the lung."
A medical term used principally in clinical and pathological contexts.
Resembling or relating to a sarcoid lesion or to sarcoidosis.

The plural is used when referring to multiple distinct sarcoid lesions or masses.

A sarcoid may look medically alarming, but the term usually refers to a nonmalignant granulomatous lesion associated with sarcoidosis.

Where does sarcoid come from?
Sarcoid was formed in the 19th century from Greek sarkos, meaning “flesh,” combined with the suffix -oid, meaning “resembling” or “like.” The same Greek root underlies words including sarcoma, sarcophagus, sarcasm, and sarcastic, although their later meanings developed along quite different lines.
