Differential Diagnosis for Pediatric Itching Rash around Eyes and Involving Neck
Single Most Likely Diagnosis
- Atopic Dermatitis (Eczema): This is the most common chronic skin condition in children, often presenting with itchy, inflamed skin that can appear around the eyes and on the neck. The condition tends to flare and remit, with triggers including allergens, irritants, and stress.
Other Likely Diagnoses
- Allergic Contact Dermatitis: This condition occurs when the skin comes into contact with an allergen, leading to an immune response and resulting in a rash. Common allergens include nickel, fragrances, and certain plants. The rash can appear anywhere, including around the eyes and on the neck.
- Seborrheic Dermatitis: Characterized by a red, itchy rash on oily areas of the body, such as the face, including around the eyes, and can extend to the neck. It's common in infants (cradle cap) and adolescents.
- Impetigo: A highly contagious bacterial skin infection that can cause red sores on the face, including around the eyes, and may spread to the neck. It's itchy and can be accompanied by honey-colored crusts.
Do Not Miss Diagnoses
- Kawasaki Disease: Although rare, this condition is critical to diagnose early due to its potential to cause coronary artery aneurysms. It presents with fever, rash, swelling of hands and feet, conjunctivitis, and cervical lymphadenopathy. The rash can appear anywhere, including the face and neck.
- Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN): A severe skin condition usually caused by medications or infections, characterized by blistering of the skin and mucous membranes. It can start with symptoms around the eyes and mouth and spread, including to the neck. It's a medical emergency.
Rare Diagnoses
- Pityriasis Alba: A mild, chronic skin condition characterized by small, round, faint patches of skin that are lighter in color, often on the face, including around the eyes. It can be slightly itchy and is more noticeable in individuals with darker skin tones.
- Granuloma Faciale: A rare skin condition that causes single or multiple, reddish-brown, bumps or patches, typically on the face, including around the eyes. It's more common in adults but can occur in children, and the lesions can be itchy.
