Differential Diagnosis for a White Head on the Left Brow
Single Most Likely Diagnosis
- Milia: A small, white or yellowish bump on the skin, often appearing on the face, including the brow area. It is usually harmless and very common.
Other Likely Diagnoses
- Sebaceous hyperplasia: A benign condition characterized by small, shiny bumps on the skin, which can appear white or yellowish due to the accumulation of sebum.
- Keratosis pilaris: A condition where small, white or light-colored bumps appear on the skin due to the buildup of keratin, though it's more common on arms and legs.
- Pilar cyst: A benign cyst that originates from the hair follicle and can appear as a firm, white bump, often found on the scalp but can occur on the brow.
Do Not Miss Diagnoses
- Basal cell carcinoma: Although less common, a basal cell carcinoma can sometimes present as a pearly white bump. Given its potential to be malignant, it's crucial not to miss this diagnosis.
- Squamous cell carcinoma: Though typically more ulcerative, in early stages, it might appear as a firm, white bump, making it essential for differential diagnosis.
Rare Diagnoses
- Trichoepithelioma: A rare, benign tumor of the hair follicle that can appear as a small, white or skin-colored bump.
- Syringoma: A benign tumor of the sweat glands that can present as small, white or yellowish bumps, more commonly found around the eyes but can occur on the brow.
- Epidermoid cyst: While not exclusively white, these cysts can appear as firm, bumps under the skin and occasionally have a white appearance due to the material they contain.
