The Dermatological Spectrum of Coronavirus Disease-19: Cutaneous Signs for Diagnostics and Prognosis and an Expanded Classification

Three years ago, researchers Wollina, Chiriac, and Karadag conducted a review on skin-related findings in COVID-19 patients. They found that cutaneous signs such as acro-ischemic lesions, rash, chilblain-like eruptions, and androgenetic alopecia were increasingly observed. These signs could be significant for early diagnosis, prognosis, and differential diagnoses of COVID-19. The findings could also have therapeutic implications and assist clinicians in triaging and optimally treating COVID-19 patients. The review aimed to classify these symptoms, document their frequency, and present treatment options for these cutaneous manifestations.
