RESUMO
Introduction: Pernio-like lesions were reported as dermatologic manifestations of COVID-19 as early as May of 2020. Since mRNA COVID-19 vaccines were introduced in December 2020, 9 reports of vaccine-associated pernio-like lesions have been presented in the medical literature. Case Presentation: A male in his 60s developed pernio-like lesions on the bilateral toes approximately 1 week after receiving the second dose of the Pfizer-BioNTech COVID-19 mRNA vaccine. His symptoms resolved in 6 weeks. Conclusion: The rising number of reports of pernio-like lesions associated with COVID-19 vaccination underlines the importance of the pathophysiological state of the vaccinated patient and how it relates to dermatological manifestations. Pernio-like lesions are thought to represent a robust host immune antiviral response related to production of interferon-1 in the setting of primary infection; incidences occurring after vaccination further support this theory. Unfortunately, media-generated reports of such reactions have the potential to inflame distrust and fear of the vaccine among the general public. Given the previous media interest in reporting pernio-like lesions with primary COVID-19 infection, it is reasonable to expect overrepresentation of pernio-like lesions with vaccination. There appears to be a general increase in patient distrust of evidence-based medicine and thus "COVID toes" represent an important intersection at which the clinician can capture the patient's trust by providing education and counseling.
