The dermatological spectrum of coronavirus disease-19 disease: Cutaneous signs for diagnostics and prognosis and an expanded classification

Abstract

During severe acute respiratory syndrome coronavirus (CoV)-2-induced CoV disease (COVID)-19 pandemic cutaneous signs of the disease gained increasing interest for early diagnosis, to establish a prognosis and for differential diagnoses. The present review aims to summarize current knowledge on cutaneous findings in COVID19. The findings are classified and described clinically. The spectrum of cutaneous signs include acro-ischemic lesions, rash, chilblain-like eruptions, and androgenetic alopecia. Their significance is given, and treatment options are presented. This may allow the clinicians to support triage and optimal treatment for COVID-19 patients. © 2020 Uwe Wollina, Anca Chiriac, Ayse Serap Karadag.
