An 82-year-old man with new skin lesions after COVID-19 vaccination.

Background

During the height of the SARS CoV-2 (severe acutre respiratory syndrome coronavirus disease 2019 [COVID 19]) pandemic, there have been numerous case reports of cutaneous reactions shortly after COVID-19 vaccine administration. Most reported cases are local injection-site reactions, whereas persistent or delayed cutaneous reactions have not been as common.

Methods

We present the case of an 82-year-old man with persistent rash after the second COVID-19 vaccination.

Results

A specific diagnosis was confirmed after the third skin biopsy.

Conclusion

Patients are frequently referred to an allergist for various cutaneous reactions that occurred after vaccination, concerned about a possible drug allergy. This case emphasizes the importance of keeping a broad differential diagnosis when encountering a persistent skin rash not resolved by oral antihistamines or steroids.
