Pityriasis Rosea Induced by COVID-19 Vaccination

It is increasingly recognized that SARS-CoV-2 infection and COVID-19 vaccines have been associated with skin disorders, including pityriasis rosea. It has been reported that pityriasis rosea has been triggered by several vaccines, as a rare side-effect. We present two cases of COVID-19 vaccine-induced pityriasis rosea. Skin lesions appeared in a 49-year-old female 8 days after the first dose of the BNT162b2 mRNA vaccine and in a 53-year-old male 7 days after the second dose of the same vaccine. The exanthem was self-limited in both patients over a period of a month. LEARNING POINTS: Physicians should be aware that pityriasis rosea is a rare side-effect of COVID-19 vaccination. Pityriasis rosea is self-limiting and no medical treatment is usually required.
