Abstract
BACKGROUND: In late December 2019, a cluster of pneumonia cases due to a novel betacoronavirus, SARS-CoV-2 was reported in China. The so-called COVID 19 is responsible not only for respiratory symptoms, from mild up to pneumonia and even acute respiratory distress syndrome, but also for extrapulmonary involvement. CASES PRESENTATION: Here we present two cases of spontaneous muscle hematoma in patients with SARS-CoV-2 infection, both on therapeutic LMWH for atrial fibrillation: the first one was an 86-year-old Caucasian female with a history of hypertensive cardiomyopathy and the second one was an 81-year-old Caucasian male with a history of hypertension, diabetes and ischemic heart disease. Blood tests revealed a considerable drop of hemoglobin and alterations of coagulation system. In both cases, embolization of femoral artery was performed. A few other cases of bleeding manifestations are reported in literature, while a lot has been published about the hypercoagulability related to COVID-19. CONCLUSIONS: Our reports and literature review highlight the need of active surveillance for possible hemorrhagic complications in patients with SARS-CoV-2 infection.
