Eosinophilic Annular Erythema Responding to Doxycycline

Eosinophilic annular erythema (EAE) is a rare skin disease characterized by relapsing and remitting pruritic, annular erythematous plaques and tissue eosinophilia. A 39-year-old male presented with a mildly pruritic, relapsing, and remitting urticarial rash. A biopsy revealed superficial and deep pe...

Sumario:Eosinophilic annular erythema (EAE) is a rare skin disease characterized by relapsing and remitting pruritic, annular erythematous plaques and tissue eosinophilia. A 39-year-old male presented with a mildly pruritic, relapsing, and remitting urticarial rash. A biopsy revealed superficial and deep perivascular dermatitis with numerous eosinophils and some neutrophils, with an absence of flame figures. Based on clinical and histopathologic findings, the patient was given a diagnosis of eosinophilic annular erythema. Treatment was initiated with doxycycline 100 mg twice daily. The patient reported substantial improvement at three months and sustained clearance at one year, remaining on doxycycline well tolerated throughout. To our knowledge, no cases of EAE improving with doxycycline have been reported in the literature and, thus, our findings highlight a potential new therapy to consider in a patient with EAE.
