Differential Diagnosis for Left Lower Eyelid Swelling
Single Most Likely Diagnosis
- Blepharitis: This is an inflammation of the eyelids that can cause swelling, redness, and itching. It's a common condition and can be caused by a bacterial or demodex mite infestation, making it a likely diagnosis for unilateral eyelid swelling.
Other Likely Diagnoses
- Hordeolum (Stye): A localized infection or inflammation of the eyelid margin, which can cause swelling, pain, and redness. It's a common condition that can occur in any part of the eyelid.
- Chalazion: A small bump on the eyelid due to a blocked oil gland, which can cause swelling and tenderness. It's more common in adults and can occur in the upper or lower eyelid.
- Allergic Reaction: An allergic reaction to makeup, cosmetics, or other substances can cause eyelid swelling, redness, and itching.
- Trauma: A blow to the eye or eyelid can cause swelling, bruising, and pain.
Do Not Miss Diagnoses
- Orbital Cellulitis: A serious infection of the tissues surrounding the eye, which can cause swelling, redness, and pain. It's a medical emergency that requires prompt treatment.
- Angioedema: A rapid swelling of the skin and mucous membranes, which can cause eyelid swelling, respiratory distress, and anaphylaxis.
- Basal Cell Carcinoma: A type of skin cancer that can cause a painless nodule or bump on the eyelid, which can lead to swelling and destruction of surrounding tissue.
Rare Diagnoses
- Sarcoidosis: A systemic disease that can cause granulomatous inflammation in various parts of the body, including the eyelids, leading to swelling and uveitis.
- Wegener's Granulomatosis: A rare autoimmune disorder that can cause inflammation and damage to blood vessels, including those in the eyelids, leading to swelling and destruction of tissue.
- Lacrimal Gland Tumor: A rare tumor of the lacrimal gland, which can cause swelling and pain in the eyelid, as well as proptosis and vision loss.
