Abstract
- As part of the efforts to overcome the ongoing coronavirus disease 2019 (COVID-19) pandemic, mass vaccination programs against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been initiated. Since then, an increasing number of cutaneous adverse events associated with the COVID-19 vaccines have been reported. Lichen planus (LP) is a rare inflammatory mucocutaneous disease with various clinical presentations, although uncommon, occurring following vaccination. There have been several cases of LP reported following COVID-19 vaccination. However, there has been no report of generalized LP following the COVID-19 vaccine to our knowledge. Herein, we report a case of generalized LP following the Oxford/AstraZeneca (AZD1222) vaccine. A 68-year-old female presented with widespread, erythematous pruritic papules and plaques on the trunk and both limbs, which developed 2 to 3 days after administration of the AZD1222 vaccine. Histopathological examinations revealed cellular interface dermatitis. The patient was diagnosed with generalized LP and was successfully treated with systemic corticosteroid and cyclosporine. As the vaccination campaign against COVID-19 is ongoing and early recognition and treatment are essential to reduce the morbidity of this condition, clinicians should be aware that LP could follow COVID-19 vaccination regardless of the type of vaccine administered.
