Cutaneous Manifestations of COVID-19

The document summarizes skin manifestations in COVID-19 patients, noting that while some symptoms like maculopapular exanthema and urticaria may not be specific to the virus, vascular lesions such as chilblain-like lesions and retiform purpura are more closely associated with SARS-CoV-2 infection. These skin symptoms can aid in early detection of asymptomatic cases and provide prognostic information. The document also indicates that chilblain-like lesions suggest a strong immune response, whereas retiform purpura indicates a poor response leading to a hypercoagulable state. It emphasizes the need for further research to understand the pathophysiology of these skin manifestations and the importance of considering COVID-19 in the differential diagnosis of skin symptoms.
