Exanthematous Eruptions in Children.

Childhood exanthems are commonly encountered by pediatricians in the hospital and the office. In the last several decades, we have seen a shift in the epidemiology of many of these diseases. After being deemed eliminated at the turn of 21st century, measles has experienced a resurgence secondary to falling vaccination rates, raising public health concerns. A new variant of hand, foot, and mouth disease caused by coxsackievirus A6 has been associated with more widespread and atypical disease, which can present diagnostic challenges to clinicians. Parvovirus B19, which is traditionally associated with fifth disease, is also the leading cause of papular purpuric gloves and socks syndrome, a rare condition with which providers may be unfamiliar. Since the introduction of routine vaccination, there has been a shift in the epidemiology and clinical presentation of primary varicella and herpes zoster. Finally, the recently described phenomenon of Mycoplasma pneumoniae-induced rash and mucositis will be discussed. [Pediatr Ann. 2020;49(3):e116-e123.].
