The polymorphic presentation of annular dermatoses in the pediatric population renders them a diagnostic challenge to the clinician. They include various distinct disease entities that can be vaguely categorized according to the age of onset. Herein, we report on a young girl with clinical characteristics of Wells' syndrome, while histological findings favored the diagnosis of annular erythema of infancy (AEI). Although morphological and histological similarities do exist, AEI and eosinophilic annular erythema (EAE) of childhood are considered as distinct entities in the literature. Wells' syndrome (WS) is an eosinophilic dermatosis and histologically characterized by eosinophilic dermal infiltration with the hallmark feature of "flame figures." Based on this case, we discuss and review the differential diagnoses of annular dermatoses in children.
