A case of Blaschkoid pityriasis rosea following COVID-19 vaccination: A rare exceptional occurrence

Abstract

The launch of COVID-19 vaccines in India has raised the expectations of the dreadful COVID-19 pandemic ending in the future. Various mild and benign cutaneous manifestations of the different forms of the COVID-19 vaccine have been documented. Herein, we are reporting a unique case of Blaschkoid pityriasis rosea (PR) developing after COVID-19 vaccination. A forty-two-year-old female presented with PR along a linear arbitrary zone on the back at the level of L1-L2 extending to involve the abdomen and an oblique zone on the thigh. She was vaccinated with the first dose of the COVISHIELD ChAdOx1/nCoV-19 (recombinant) coronavirus vaccine six days before the onset of the lesions. There are only several case reports of typical pityriasis rosea occurring after COVID-19 vaccination. Our unique case depicts the occurrence of atypical PR after COVID-19 vaccination.
