An Unusual Case of Arm Pain in a Young Soccer Player: Herpes Zoster in the Pediatric Athlete

Herpes zoster (HZ), shingles, is caused by the varicella-zoster virus (VZV). HZ develops as a reactivation of latent VZV and is characterized by a painful, vesicular rash typically manifesting in a dermatomal distribution on the arms, trunk or face. HZ occurs in individuals who had primary VZV disease (chickenpox) as a child or in those who have received live, attenuated VZV vaccine. HZ is common in the elderly and the immunocompromised, with age being the single greatest risk factor. The incidence of HZ in children is 74/100,000 person years for the unvaccinated and 38/100,000 person years for the vaccinated. We discuss the case of a 12-year-old soccer player with HZ who presented with right arm pain after a putative traumatic event. Diagnosis was made after two emergency department visits where the condition was not identified. HZ should be considered in the clinician's differential even in immunocompetent, vaccinated children.
