Unmasking sarcoidosis following SARS‐CoV‐2 vaccination: A case report

Sarcoidosis is an inflammatory and granulomatous disorder, developed due to dysregulation between immune response and certain environmental antigens. We hereby report an interesting case of sarcoidosis following COVID‐19 vaccination (COVIran Barekat), which presented with inflammation of previous tattoo sites as well as the development of erythema nodosum and systemic lymphadenopathy, suggested a possible link between the COVID vaccination and dysregulation of the inflammatory process and served as a reminder for clinicians to have enough vigilance before proposing a vaccine booster to these patients. We presented an interesting case of sarcoidosis with systemic involvement following COVID‐19 vaccination, which could be an important issue since a mass vaccination campaign has been initiated worldwide.
