Pemphigus vulgaris after the second dose of COVID-19 vaccination: a case report

As many people worldwide have been vaccinated, more triggered autoimmune bullous diseases have been noticed. We reported a case of new-onset pemphigus Vulgaris after COVID-19 vaccinations.

A 50 years old Syrian female presented with multiple erosions on her extremities, in addition to oral erosions and genital ulcers, after the 2nd dose of the mRNA COVID-19 vaccine. The lesions were multiple tenders and well-defined, reddish erythematous oral ulcers. At the same time the Skin examination showed hyper-pigmented patches over the extremities, a sequel of ruptured bullae. Pemphigus Vulgaris was diagnosed by histology. She continued on 35 mg/day of prednisone for another 2 weeks.

Pemphigus is not a contraindication to vaccination, although it may be worse or present as a first onset.
