INTRODUCTION
Over 40 million cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for coronavirus disease 2019 (COVID-19), have been reported in the United States (US).1 Pulsipher et al.2 previously compared the cutaneous manifestations of COVID-19 and adverse effects of remdesivir, an antiviral drug approved by the US Food and Drug Administration (FDA) for SARS-CoV-2. This present survey of Actemra (tocilizumab), a recombinant humanized interleukin 6 (IL-6) receptor antagonist, aims to distinguish COVID-19 disease manifestations from adverse drug reactions.3
Cutaneous changes from COVID-19 and tocilizumab are reported in the literature and summarized in Table 1. Tocilizumab adverse reactions include serious skin infections (i.e., cellulitis and necrotizing fasciitis) and cutaneous eruptions.6–8
A cross-sectional study of tocilizumab treatment for COVID-19 reports associated morbilliform (10% of n=80) and other maculopapular (2.8% of n=36) eruptions.11 Prospective cohort analysis (n=51) similarly found a nonspecific cutaneous
Tocilizumab, FDA-approved for rheumatoid arthritis, giant cell arteritis, juvenile idiopathic arthritis, and cytokine release syndrome, received emergency use authorization for hospitalized COVID-19 patients requiring oxygen, mechanical ventilation, or extracorporeal membrane oxygenation.4 Tocilizumab may lower risk of mortality, hospital length of stay, and mechanical ventilation requirements.5

Maculopapular rash and urticarial lesions characterize the prominent cutaneous manifestations of COVID-19.9,10
