Differential Diagnosis for Rash with Burning Sensation on Back of Neck
Single Most Likely Diagnosis
- Contact Dermatitis: This is a common condition that occurs when the skin comes into contact with an irritant or allergen, leading to a rash and potentially a burning sensation. The back of the neck is a common area for contact dermatitis due to exposure to allergens or irritants from clothing, jewelry, or hair products.
Other Likely Diagnoses
- Eczema (Atopic Dermatitis): Characterized by itchy, inflamed skin, eczema can also cause a burning sensation and is common in areas like the neck.
- Psoriasis: An autoimmune condition that speeds up the life cycle of skin cells, causing cells to build up rapidly on the surface of the skin. The back of the neck is a typical area for psoriasis lesions, which can be itchy and feel like they're burning.
- Seborrheic Dermatitis: A condition causing scaly patches, red skin, and stubborn dandruff, often accompanied by a burning sensation. It can occur on the neck.
Do Not Miss Diagnoses
- Meningitis: Although rare, meningitis is an infection of the protective membranes covering the brain and spinal cord, known as the meninges. A rash, especially one that doesn't fade under pressure, can be a sign of meningitis, which is a medical emergency. The burning sensation could be confused with the severe headache often associated with meningitis.
- Lyme Disease: Caused by a tick bite, Lyme disease can lead to a distinctive rash (erythema migrans) and neurological symptoms. Early recognition is crucial for effective treatment.
- Shingles (Herpes Zoster): Characterized by a painful rash, shingles can cause a burning sensation. It's essential to diagnose and treat shingles promptly to prevent complications like postherpetic neuralgia.
Rare Diagnoses
- Pityriasis Rubra Pilaris (PRP): A rare skin disorder that causes constant itching and scaling (exfoliation) of the skin, potentially leading to a burning sensation.
- Keratosis Pilaris: A condition that causes rough patches and small, acne-like bumps on the skin, which can sometimes feel like they're burning, especially if irritated.
- Dermatomyositis: An inflammatory disease characterized by skin rash and muscle weakness, which can present with a burning sensation due to skin involvement.
