Abstract
Eosinophilic cellulitis (EC) is a skin disease characterized by pruritic, non-purulent, erythematous plaques and histologically by edema and eosinophil infiltration in the dermis. The etiopathogenesis of the disease is not fully elucidated. It differs from infectious cellulitis by being unresponsive to antibiotics and recurring. This case report presents a late-diagnosed case of EC in a patient who did not respond to long-term and broad-spectrum antibiotics. This case underscores the importance of skin biopsy and histopathological diagnosis in patients with recurrent, non-responsive, antibiotic-resistant, and cellulitis-like clinical features resembling infectious cellulitis; "eosinophilic cellulitis" should be considered in the differential diagnosis.
