Vulvar aphthous ulcer after COVID-19 vaccination.

Vulvar aphthous ulcer, also known as acute genital ulceration or Lipschutz ulcers, is an uncommon, non-sexually acquired condition characterized by sudden onset ulcerations of the vulva in young girls and women. It is thought to represent an immunologic reaction to an infection or other source of inflammation and is commonly preceded by prodromal symptoms including fever, chills, fatigue, and malaise. During the COVID-19 pandemic, vulvar aphthous ulcer associated with COVID-19 infection has been reported. Here, we report a case of vulvar aphthous ulcer in response to COVID-19 vaccination.
