Asymmetric periflexural exanthem of childhood (APEC) is a self-limited disease characterized by unilateral exanthem. The etiology is unknown, but a viral agent is suspected. Most often there is no formal proof of an associated viral etiology, but several associations between APEC and some viruses have been described. We report a 2-year-old girl with APEC associated with influenza A. This case allows us to provide an additional argument on a probable viral etiology of APEC and a possible etiologic role of influenza A.
