Does eczema herpeticum cause crusting skin?

Eczema herpeticum is a viral infection affecting skin that may already have eczema or another disrupted barrier. Lesions can be grouped closely, feel tender rather than simply itchy, and change quickly from blisters or punched-out erosions to moist crusted areas. The face, neck, and areas with active eczema can be involved.

Crusting alone has many possible explanations, including healing irritation or bacterial infection. The combination of rapidly worsening painful spots, new blisters, and a person who feels unwell deserves medical attention rather than home treatment alone.

Contact a clinician promptly if eczema herpeticum is suspected. Antiviral treatment may be needed, and early evaluation helps determine whether the eyes or other sensitive areas are involved. Until reviewed, avoid scratching, sharing towels, or applying new active creams to the affected skin. Wash hands after touching the area and keep it gently covered if it is oozing.

Do not rely on antibiotic cream or leftover steroid medicine without advice; these do not replace assessment for a viral infection and may obscure how the rash is changing.

Seek urgent medical care for rapidly spreading painful crusted lesions, fever, marked tiredness, eye pain, light sensitivity, blurred vision, or lesions close to the eye. Babies, people with weakened immune systems, and anyone who is becoming generally unwell should be assessed without delay.

Ask whether the lesions need testing, whether antiviral treatment is appropriate, how to protect the eyes and close contacts, and which eczema medicines should be paused or continued. Tell the clinician when the pain, blisters, crusting, and any fever began.
