Cutaneous manifestations of COVID-19
Coronavirus disease 2019 has several cutaneous manifestations. The American Academy of Dermatology reports that skin lesions like morbilliform rashes (22%), pernio-like rashes(18%), urticaria (16%), macular erythema (13%), vesicular purpura (11%), papulosquamous purpura (9.9%) and retiform purpura (6.4%) are seen in people with COVID-19.[1][2][3] Pernio-like lesions were more common in mild disease while retiform purpura was seen only in critically ill patients.[1] The major dermatologic patterns identified in individuals with COVID-19 are urticarial rash, confluent erythematous/morbilliform rash, papulovesicular exanthem, chilbain-like acral pattern, livedo reticularis and purpuric “vasculitic” pattern.[4] Chilblains and Multisystem inflammatory syndrome in children are also cutaneous manifestations of COVID-19.[5]
Urticarial rash[edit]
Urticarial rash is seen in several bacterial and viral infections, so COVID-19 is no exception. These rashes are more commonly found in the trunk and limbs, relatively sparing the acral sites. Systemic corticosteroids are a therapeutic option for urticarial rash induced by COVID-19.[4]
Confluent erythematous rash[edit]
The erythematous rashes seen in COVID-19 are mostly present on the trunk and limbs, and associated with itching.[4] Exanthems induced by viruses other than COVID-19 and drug reactions should be considered as differential diagnosis in the case of erythematous rashes.[4]
Livedo reticularis[edit]
Livedo reticularis refers to slowing of blood flow, leading to desaturation of blood and bluish discolouration of the skin. This type of skin rashes may be seen in cold-induced vasoconstriction as seen in polycythemia or other causes leading up to focal impairment of blood flow.[4]
