Cutaneous Manifestations of COVID-19: Characteristics, Pathogenesis, and the Role of Dermatology in the Pandemic.

Cutaneous manifestations of COVID-19-SARS-CoV-2-are common and varied. Morbilliform, vesicular, and urticarial eruptions may be nonspecific initial features of the disease. Chilblainlike lesions on the fingers or toes typically occur as part of a resolution phase, signifying a milder course, whereas livedoid lesions and retiform purpura are associated with coaguloapthy and more severe disease. Additionally, a severe Kawasaki-like multisystem inflammatory syndrome rarely is seen in children. This diverse range of cutaneous manifestations in COVID-19 reflects a spectrum of host immunologic responses to SARS-CoV-2 and may inform disease pathophysiology.
