What is the condition characterized by granulated inflammation of the eyelid that may require surgical removal?

A chalazion is a condition characterized by a blocked meibomian gland in the eyelid, leading to the formation of a localized swelling that can become inflamed, presenting as a granulated lump. When conservative measures to manage a chalazion, such as warm compresses or corticosteroid injections, are ineffective, surgical intervention may be required to remove the lesion, especially if it affects vision or causes significant discomfort.

In contrast, hordeolum, commonly known as a stye, is an acute infection of the eyelid typically caused by bacteria, resulting in a painful red bump. While it may also require treatment, it usually resolves on its own without the need for surgical removal.

Conjunctivitis is an inflammation of the conjunctiva, which does not specifically involve the eyelid in the same manner as a chalazion and is typically managed with topical medications rather than surgical intervention.

Blepharitis refers to inflammation of the eyelid margins, often due to bacterial infection or seborrheic dermatitis, and is generally managed with cleanliness and topical treatments rather than surgery.

Thus, the unique characteristics of a chalazion and the potential need for surgical removal when conservative treatments fail make it the correct answer.
