rash necessitating drug discontinuation in one patient.12 Furthermore, development of a pruritic generalized cutaneous toxic erythematous rash with eosinophilia (similar to DRESS syndrome) was also reported in a SARS-CoV-2 patient receiving tocilizumab treatment.13
As cutaneous manifestations of COVID-19 and adverse dermatologic reactions of tocilizumab overlap, distinguishing disease and drug effects is imperative. Sharing and reporting cutaneous findings will be an important role of dermatologists as we deepen our understanding of novel SARS-CoV-2 manifestations. As cases of SARS-CoV-2 continue to rise, increased use of tocilizumab will require greater attention to potential cutaneous toxicity.
