AbstractCoronavirus disease (COVID-19) chilblains is a well-reported cutaneous pattern of severe acute respiratory syndrome coronavirus (SARS-CoV-2). Through this narrative review, we provide an evidence-based overview of idiopathic and secondary chilblains, distinguishing features of COVID-19 chilblains, and a systematic clinical approach to history, examination, investigations, and treatment. In the absence of cold or damp exposure, COVID-19 should be considered as a cause of acute chilblains. The timing of onset of COVID-19 chilblains relative to active SARS-CoV-2 viremia remains unclear. Patients with suspected COVID-19 chilblains should thus follow public health guidelines for COVID-19 testing and self-isolation.
