Eosinophilic Cellulitis (Wells Syndrome) in a Pediatric Patient: A Case Report and Review of the Literature

We report a 4-year-old boy who presented with multiple pruritic, annular, erythematous plaques on the lower extremities of 1 week's duration. Histopathology of an affected area revealed a dense dermal infiltrate of eosinophils and flame figures without evidence of vasculitis. A diagnosis of eosinophilic cellulitis (EC), or Wells syndrome, was made. The patient had an excellent response to topical and systemic steroids following 1 week of treatment. This case appeared to be idiopathic, as there was no cause identified such as arthropod bites or tinea infection. The patient's EC cleared and has not had a recurrence. Cutis. 2012;89:191-194.
