Common Annular Lesions in the Pediatric Population: Part 1.

Dermatologic presentations can quickly become overwhelming for clinicians due to the vast number of causes for these conditions. Characteristics of a rash, such as shape, color, size, and distribution, can significantly narrow the differential diagnosis. A solid framework to organize these presentations is critical for correctly identifying and treating skin issues. The shape of a rash, for instance, can serve as a foundation from which to build complex differential diagnoses. Annular rashes in the pediatric population are common complaints requiring clinical evaluation. This article is the first part of a two-part review that discusses some of the most frequent causes of these annular lesions in the pediatric population. Knowledge of these rashes can drastically improve a physician's ability to manage dermatologic issues. [Pediatr Ann. 2019;48(2):e92-e96.].
