The pathogenesis of erythema annulare centrifugum (EAC) is unknown, but it is probably due to a hypersensitivity reaction to a variety of agents, including drugs, arthropod bites, infections (bacterial, mycobacterial, viral, fungal, filarial), ingestion (blue cheese Penicillium), and malignancy.
The most common cause of annular lesions encountered in the adult population is dermatophytosis, which may be successfully diagnosed without a biopsy. However, other conditions may present with much the same appearance (Table 1).
