Background
- Diffuse HSV infection occurring in 3% of patients patients with atopic dermatitis[1]
- May be life-threatening
Clinical Features
- Development of vesicular eruptions containing HSV 1 or 2 in areas of epidermis previously affected by atopic dermatitis
- Lesions may appear similar to impetigo[2]
- Fever is common
- Multiple organ systems can become involved, resulting in lymphadenopathy, keratoconjunctivitis (potentially sight-threatening),meningitis, encephalitis, etc [3].
- Lesions may become secondarily infected by bacteria, mainly with staph aureus[4].
- The following is associated with increased susceptibility to Eczema Herpeticum[5]:
- Early age of onset of eczema
- History of food allergies or asthma[6]
- Larger surface area of eczema
- Eczema of the head/neck
- Increased levels of IgE

- Herpes gingivostomatitis
- Herpes keratitis
- Herpes labialis (cold sore)
- Herpes simplex encephalitis

- Impetigo
- Eczema Vaccinatum
- Primary varicella infection
Evaluation[9]
- Clinical
