Dermatological Manifestations Associated With COVID-19 and COVID-19 Vaccination: Results From the Lebanese COVID Registry

The study "Dermatological manifestations associated with COVID‐19 and COVID‐19 vaccination: results from the Lebanese COVID registry" conducted an observational cross-sectional study on 142 patients (133 adults and 9 pediatric patients) from May 2021 to May 2022. The main dermatological manifestations reported with COVID-19 infection in the adult group were urticaria (32.9%), telogen effluvium (21.4%), morbilliform (10%), and papulosquamous (8.6%) eruptions. Urticaria was also the most common adverse cutaneous reaction to the vaccine (33%). Interestingly, herpes zoster was triggered in 12 patients post vaccination, more frequently seen in patients above the age of 41 (P = 0.013). In the pediatric group, the most reported dermatological findings associated with COVID-19 infection were malar erythema (25%) and telogen effluvium (25%). One 16-year-old patient developed lichen planus after one dose of a COVID-19 vaccine. No deaths were reported in both age groups. The study concludes that the clinical manifestations of the COVID-19 virus and vaccine are diverse, and more studies are necessary to establish the pathophysiology of these dermatological findings.
