Herpes zoster in Child
Although the onset of cutaneous zoster in adults typically involves a 1-3 day prodrome of burning pain or tingling in the affected dermatome, this is rarely observed in children. Postherpetic neuralgia is also rare in children.
If it occurs, zoster encephalitis usually appears in the first 2 weeks after the onset of lesions and has a 10%-20% mortality rate. Disseminated zoster occurs 5-10 days after the onset of dermatomal disease. It is defined as more than 20 lesions outside the initial dermatome of involvement.

- Herpes simplex virus infection occurring within a dermatomal distribution is the primary differential diagnosis. Serology, viral culture, or polymerase chain reaction (PCR) may be necessary to distinguish this diagnosis from zoster.
- Allergic contact dermatitis may present as a well-defined vesicular plaque. A dermatomal distribution suggests zoster.
- Molluscum contagiosum, when inflamed, can be confused with varicella-zoster. Cases are typically of longer duration, and VZV PCR studies are negative. The presence of coexisting noninflamed molluscum lesions is a helpful diagnostic clue.
