Differential Diagnosis for White Color Around Mouth

  • Single Most Likely Diagnosis
    • Angular cheilitis: This condition is characterized by inflammation of the corners of the mouth, often causing a white appearance due to fungal or bacterial infection, and is commonly seen in individuals with poor oral hygiene, nutritional deficiencies, or those who wear dentures.
  • Other Likely Diagnoses
    • Oral thrush: A fungal infection that can cause white patches around the mouth, including the lips, and is often associated with immunocompromised states or antibiotic use.
    • Fordyce spots: Small, white or yellowish spots on the lips that are caused by the abnormal presence of sebaceous glands in the mucous membrane, which are usually harmless but can be cosmetically concerning.
    • Lip eczema (eczematous cheilitis): An inflammatory condition of the lips that can cause dryness, redness, and sometimes a white appearance due to scaling, often related to allergic reactions or irritants.
  • Do Not Miss Diagnoses
    • Squamous cell carcinoma: Although less common, a white patch or lesion around the mouth could be an early sign of oral cancer, especially in smokers or those with a history of tobacco use. Early detection is crucial for effective treatment.
    • Lichen planus: An autoimmune condition that can affect the mucous membranes inside the mouth, sometimes presenting with white, lacy patches, and can be associated with other systemic autoimmune diseases.
  • Rare Diagnoses
    • Sjögren's syndrome: An autoimmune disorder that can cause dry mouth and lips, potentially leading to a white appearance due to decreased saliva production, which is essential for oral health.
    • Leukoplakia: A condition where thick, white patches or lesions develop on the tongue, the inside of the cheeks, or on the lips, often associated with chronic irritation and has the potential to become cancerous over time.
