Pityriasis rosea and pityriasis rosea-like lesions associated with COVID-19: A new data literature review

Pityriasis rosea (PR) is a self-limiting dermatosis characterized by an initial herald patch, followed by the emergence of oval-shaped lesions that typically arrange themselves in a “Christmas tree” pattern on the trunk and proximal limbs. This condition predominantly affects females and younger individuals. Although human herpesviruses 6 and 7 (HHV-6 and HHV-7) have been hypothesized as potential etiological agents, recent observations during the coronavirus disease 2019 (COVID-19) pandemic have indicated correlations between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19 vaccinations with the occurrence of PR or PR-like eruptions, as documented in contemporary medical literature. This review synthesizes the latest studies from 2024 and 2025 that investigate the relationship between PR and COVID-19, addressing both infection-related factors and vaccine-associated implications.
