Asymmetric periflexural exanthem of childhood is a benign and self-limited disease that characteristically occurs in infants and preschool children with a female predominance. The aetiology is unknown, although it has been mainly linked to viral infections. Diagnosis is clinical and treatment is mainly symptomatic. Despite being a common disease, it is unknown and consequently underdiagnosed. Our goal is to help improving the knowledge of this disorder. We present a clinical case of a patient diagnosed with asymmetric periflexural exanthema with a history of acute pyelonephritis the previous week of the skin lesion onset.
