Differential Diagnosis for Intermittent Irritated Burning Sensation on Skin Under Nose
- Single Most Likely Diagnosis
- Contact dermatitis: This is the most likely diagnosis due to the location under the nose, where irritants such as fragrances, soaps, or other chemicals from cosmetics or tissues can easily come into contact with the skin, causing an irritated burning sensation.
- Other Likely Diagnoses
- Irritant contact dermatitis from nasal secretions: Frequent wiping of the nose can lead to irritation of the skin under the nose, especially if tissues or hands are not clean.
- Allergic contact dermatitis: An allergic reaction to substances like nickel in jewelry, certain cosmetics, or ingredients in soaps and lotions can cause a burning sensation.
- Seborrheic dermatitis: This condition can cause a burning sensation and irritation, particularly in areas rich with sebaceous glands, including the face.
- Do Not Miss Diagnoses
- Basal cell carcinoma or squamous cell carcinoma: Although less common, skin cancers can present with non-specific symptoms like irritation or burning, especially if they become ulcerated or infected.
- Lupus: Systemic lupus erythematosus can cause a malar rash that may include the area under the nose and can be accompanied by a burning sensation.
- Sarcoidosis: This condition can cause skin lesions that may feel irritated or burn, though it's less common under the nose.
- Rare Diagnoses
- Neurological disorders: Certain conditions like trigeminal neuralgia can cause facial pain that might be perceived as a burning sensation, though this would typically be more severe and possibly accompanied by other neurological symptoms.
- Infections: Though rare, infections like impetigo or fungal infections can cause irritation and a burning sensation on the skin under the nose, especially in immunocompromised individuals.
