What is the typical location of a chalazion?

• A. Usually on the upper eyelid but can occur anywhere on the eyelid.
• B. Lower eyelid only.
• C. Inside the eyeball.
• D. On the eyelashes.

Answer: (A)

Chalazion is a lump that results from blockage of a meibomian gland in the eyelid, leading to a sterile granulomatous inflammation. The typical location is on the eyelid, most often in the upper lid, though it can occur anywhere along the eyelid. It is not located inside the eyeball or on the eyelashes, which would point to completely different conditions (intraocular processes or lash-margin lesions). So the best description is a lump on the upper eyelid, with the possibility of appearing anywhere on the eyelid.
