This paper describes a case of antiphospholipid syndrome-like condition caused by coronavirus disease 2019. The medical community still faces many diagnostic and therapeutic challenges vis-à-vis coronavirus disease 2019. Ultimately, coronavirus disease 2019 is diagnosed on the basis of laboratory and radiological findings. Considering the high rate of mortality due to coagulation abnormalities and thrombosis among coronavirus disease 2019 patients, it is important to pay attention to the differential diagnoses of coronavirus disease 2019 and other diseases following thrombotic events.

The patient was a 56-year-old Iranian man who underwent coronary artery bypass graft surgery and mitral valve repair. During hospitalization, the patient showed an elevated level of anticardiolipin antibody (immunoglobulin G isotype), antiphospholipid antibodies, and thrombosis in the brachial artery of the left hand, based on which a differential diagnosis of antiphospholipid syndrome was made. However, ultimately, the COVID-19 polymerase chain reaction test and computed tomography scan of the lungs showed that the patient had coronavirus disease 2019.

Conclusively, according to the few studies performed on coronavirus disease 2019 patients, elevated levels of the isotypes of antiphospholipid antibodies in coronavirus disease 2019 patients create conditions similar to antiphospholipid syndrome, which, in the absence of reliable coronavirus disease 2019 testing, can lead to misdiagnosis and consequently delayed or improper treatment. Therefore, to provide timely and appropriate treatment, it is important to pay attention to differential diagnosis.
