In this photograph, a chalazion can be seen on the patient’s upper eyelid image. These cysts commonly occur in this location due to the higher density of meibomian glands on the upper lid. (Courtesy Moran Eye Center.)

Chalazion is characterized by chronic granulomatous inflammation including multinucleated giant cells image, plasma cells image, and lymphocytes image. Note a fat globule within a granuloma image.
