Shingles in Pediatrics: A Reminder Against Age-Based Assumptions

Area of Science:

• Infectious Diseases
• Virology
• Dermatology

Background:

• Herpes zoster (shingles) is caused by the varicella-zoster virus (VZV).
• Shingles typically affects older adults or immunocompromised individuals due to declining cell-mediated immunity.
• Age is a key factor in diagnosing VZV reactivation, but can be misleading in atypical cases.

Observation:

• A previously healthy, fully immunized 10-year-old girl presented with a painful, dermatomal vesicular rash on her left arm.
• The patient had no significant medical history, including no VZV infection in the first year of life or in utero.
• Herpes zoster is uncommon in healthy children without specific risk factors.

Findings:

• The case demonstrates a VZV reactivation in a pediatric patient who does not fit the typical demographic profile for shingles.
• The clinical presentation of a dermatomal rash was consistent with herpes zoster, despite the patient's age and health status.

Implications:

• Physicians should consider VZV reactivation in children presenting with dermatomal rashes, even without typical risk factors.
• This case underscores the importance of avoiding age-based diagnostic assumptions for herpes zoster.
• Broadening differential diagnoses in pediatric dermatology is crucial for accurate and timely VZV management.
