Differential Diagnosis for White Bump Inside Eyelid
- Single Most Likely Diagnosis
- Chalazion: A common, benign condition characterized by a small, usually painless, lump or bump on the eyelid due to a blocked oil gland. The justification for this being the most likely diagnosis is its high prevalence and the typical presentation of a white bump inside the eyelid.
- Other Likely Diagnoses
- Stye (Hordeolum): An acute, localized infection or inflammation of the eyelid margin involving hair follicles of the eyelashes (external hordeolum) or meibomian glands (internal hordeolum). It presents as a painful, red bump and can appear white if it becomes abscessed.
- Meibomian Cyst: Similar to a chalazion but often larger and can be more chronic. It's a retention cyst of the meibomian gland and can present as a white or translucent bump.
- Xanthelasma: A condition characterized by small, yellowish patches or bumps on the eyelids due to accumulation of fat, but can sometimes appear white. It's more common in individuals with high cholesterol.
- Do Not Miss Diagnoses
- Basal Cell Carcinoma: Although less common, basal cell carcinoma can present as a bump on the eyelid. Given its potential for malignancy, it's crucial not to miss this diagnosis, despite its lower likelihood.
- Squamous Cell Carcinoma: Another form of skin cancer that can appear on the eyelid, presenting as a bump or lesion. Early detection is key for effective treatment.
- Rare Diagnoses
- Sebaceous Cell Carcinoma: A rare, aggressive form of cancer that originates in the oil glands of the eyelid. It can masquerade as a benign condition like a chalazion or stye, making it important to consider in the differential diagnosis.
- Kaposi’s Sarcoma: A rare cancer that can cause lesions on the skin, including the eyelids, especially in immunocompromised individuals.
- Sjögren’s Syndrome: An autoimmune disorder that can cause dry eyes and potentially lead to bumps or lesions on the eyelids due to inflammation or secondary infections.
