A potential misdiagnosis in the COVID-19 pandemic era: superimposed
thrombosis or recurrence
The clinical manifestation of coronavirus disease 2019 (COVID-19)
overlap with other disorders especially cardiovascular diseases (CVD).
We report a 58 years old female presented with syncope episodes and
dyspnea on exertion with the left atrial mass, candidate for surgical
removal and mitral valve replacement. Nearly 3 months later, she
developed dyspnea, fever, and a sore throat cause to admit her with
suspected COVID-19. During diagnostic evaluation, a larger LA mass
detected that seemed to be COVID-19 induced organized thrombus with
prosthetic mitral valve malfunction. the mass resected and
immunohistochemistry revealed liposarcoma. The unusual early recurrence
of liposarcoma and misdiagnosis with COVID-19 induced thrombosis are the
hallmark of the present case.
