ABSTRACT
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.
ABSTRACT
Development of pemphigus foliaceus (PF) following SARS-CoV-2 infection has only been reported in one patient who had received Bamlanivimab and thus might be considered as a drug-induced case of PF. Here, we reported the first case of PF arising solely after COVID infection without taking any culprit drug.
