Eczema Herpeticum Complicating Atopic Dermatitis: A Rare Presentation

Area of Science:

• Pediatric Dermatology
• Infectious Diseases

Background:

• Atopic dermatitis (AD) is a prevalent global skin condition impacting quality of life and increasing infection risk.
• Infantile AD presents unique diagnostic challenges, especially when initial symptoms resemble common conditions like cradle cap.

Observation:

• A four-month-old infant with a history of AD developed yellow, scaly scalp lesions initially mistaken for cradle cap.
• Clinical worsening included the appearance of vesicles, prompting emergency room referral.
• Laboratory tests revealed severe eosinophilia and elevated total IgE levels.

Findings:

• The clinical presentation and laboratory findings strongly suggested eczema herpeticum (EH), a severe herpes simplex virus (HSV) infection.
• Intravenous acyclovir and antibiotics were administered due to concerns of secondary infection and systemic spread.
• Skin lesions resolved within six weeks following treatment and follow-up care.

Implications:

• Eczema herpeticum is a dermatological emergency requiring swift intervention to prevent severe morbidity.
• This case highlights the importance of considering EH in infants with AD experiencing sudden skin deterioration.
• Early recognition and management are key to successful outcomes in this rare but potentially life-threatening condition.
