Skin Lesions Observed in COVID-19 Infection

The document discusses the cutaneous manifestations associated with COVID-19, classifying skin lesions into six patterns using the acronym "GROUCH." It highlights that chilblain-like lesions are more common in younger patients with fewer systemic symptoms, while purpuric and livedoid lesions are more frequent in elderly patients with severe COVID-19. Long-term symptoms post-COVID-19 include fatigue, headache, attention disorder, hair loss, and dyspnea, with hair loss often attributed to telogen effluvium, typically resolving within 6 months. Skin reactions have also been reported post-vaccination, notably the "COVID-arm," predominantly in women, possibly due to a cross-reaction with polyethylene glycol. The exact mechanisms behind these cutaneous manifestations remain unclear, emphasizing the importance of considering COVID-19 history and vaccination status during consultations.
