Introduction: The SARS-CoV-2 virus causes COVID-19, a disease linked to skin
symptoms including rash, erythema, and urticaria. However, the exact
mechanisms by which COVID-19 leads to these skin changes are not fully
understood. Our review aimed to analyze the main skin issues linked to COVID-
19 and any possible underlying biological pathways in COVID-19 patients.
Design of the study: Systematic review. Methods: Between January 1, 2020, and
December 10, 2022, the authors conducted a bibliographic search in the databases
PubMed, B-on, Scopus, and Web of Science, in order to collect revalent studies.
Inclusion criteria included case series or comparative studies of COVID-19
cutaneous manifestations in various age ranges. Results: The evaluation found 26
articles that met the inclusion criteria, including case reports, series, and
observational studies. The investigations comprised 547 people with COVID-19
who had skin symptoms. A systematic analysis of the literature on skin
manifestations in COVID-19 discovered that erythema was the most common skin
symptom, occurring in 44.18% of the 547 individuals included in the research. Skin
lesions appeared 9.92 days after the onset of systemic symptoms such as fever,
cough, and trouble breathing. Other skin signs were chilblain-like lesions,
urticaria-like lesions, vesicular lesions, livedo/necrosis, and petechiae. 44.77% of
patients reported significant itching. The most common systemic symptom among
the 431 patients with information on this was fever, followed by coughing,
exhaustion, difficulties breathing, headaches, gastrointestinal issues, and a loss of
smell or taste. Conclusion: Understanding of the most common skin issues related
to the infection of COVID-19 would help in early diagnosis of COVID-19 and
improve the patients outcomes. The current review provided a comprehensive
overview of the skin disorders related to COVID-19 and its potential causes.
Future studies should be large and well-designed.
