Giant cell myocarditis following COVID-19 successfully treated by immunosuppressive therapy.

It has been shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by coronavirus disease 2019 (COVID-19), can lead to multi-organ impairment including cardiac involvement and immunological problems. Acute myocarditis is one of serious and fatal complications of COVID-19. In this case report, we present a 46-year-old lady with a history of lichen planus dermatitis who has developed a rapidly progressive heart failure after an episode of COVID-19. The pathologic examination of her endomyocardial biopsy specimens was compatible with GCM, and she was successfully treated with a combined immunosuppressive therapy regimen.
