A chalazion is a swelling or lump in the eyelid, caused by inflammation of one of the small oil-producing glands located in the upper and lower eyelids. When a chalazion is of sudden onset and acutely inflamed, it is called a stye. Sometimes a chalazion can cause the entire eyelid to swell suddenly, but usually there is a particular tender point.
