Lichen planus (LP) is a T cell‐mediated chronic inflammatory disorder. Several clinical variants based on lesion morphology and localization are reported. LPP remains uncommon with an unknown etiology. Besides, some precipitating factors have been suggested in the literature including hepatitis C infection; restrictive underwear, localized friction, and sun exposure.(1, 2) Herein, we present a case of new‐onset of LPP following the ChAdOx1 nCoV‐19 (Oxford‐AstraZeneca) vaccine. A literature review was also conducted to summarize the various cases of LP induced and/or trigged by Covid‐19 vaccine.
