A 57-year-old man was admitted in order to be treated for coronavirus disease 2019 (COVID-19). He had no past medical history, taking no medications or supplements. He has no history of COVID-19 vaccination. His main symptom was fever for three consecutive days. On admission, he also complained of mottled skin on his extremities appeared in the morning of the day before admission (Picture 1, ​,2).2). His vital signs were stable and laboratory data did not show any blood coagulation abnormalities. His symptoms gradually improved as he demonstrated mild COVID-19 and consequently he was discharged on day 5 after hospitalization while his skin lesions still had not completely disappeared.

Freeman et al. reported that livedo reticularis-like lesions were observed in 3.5% of all cutaneous manifestations with COVID-19 (1). Since livedo reticularis is caused by a disturbance of the blood flow, it reminds us of the hypercoagulable state among COVID-19 patients. However, most of the livedo reticularis-like lesions associated with COVID-19 tend to be mild and transient, which is not associated with any thromboembolic events (2). When we encounter livedo reticularis-like lesions associated with COVID-19, we should observe it carefully but not administer any excessive treatments.
