Bullous eosinophilic annular erythema

Abstract

Eosinophilic annular erythema is an idiopathic acute eosinophilic dermatosis. It is a rare condition, with approximately 30 cases reported in the English literature. It features annular, figurate urticarial edematous plaques primarily affecting the trunk and proximal limbs. During evaluation of a patient, secondary causes of eosinophilic inflammation such as allergy-related conditions (eczema, drug, urticaria, contact dermatitis), parasitic infestations, and autoimmune dermatoses will need to be excluded. We present an unusual case of a 47-year-old patient who developed this condition.
