This article is protected by copyright. All rights reserved We describe the case of an 81-year-old male admitted for bilateral pneumonia, with a negative initial swab for COVID-19. Blood tests showed an elevated C-reactive protein (26.97mg/dL) and procalcitonin (2.09ng/mL), leucocytosis (12.8x10 9 /L) with neutrophilia (11.45x10 9 /L) and lymphopenia (0.74x10 9 /L), and elevated D-dimers (4708ng/mL). Platelet count and coagulation tests were normal, and the patient didn't take antiaggregants or anticoagulants. He started empiric antibiotherapy, and blood cultures were negative. One week later he developed petechial lesions confined to fingers and toes, that progressed in a few days to haemorrhagic bullae and necrotic plaques on the hands and feet (Figure 1 ) Although there is much to discover about SARS-CoV-2 and its manifestations, abnormal coagulation results, especially elevated D-dimers and fibrin degradation products have been associated with poor prognosis, and disseminated intravascular coagulation (DIC) is common in critically ill COVID-19 patients. 9 Manalo et al. 4 
hypothesized that the microthromboses that manifest in other organs and as DIC in critically ill COVID-19 patients were the most plausible aetiology for LR, and that manifestations could vary from transient LR in milder cases to acrocyanosis in critically ill patients. Findings from minimally invasive autopsies showed degeneration and necrosis of parenchymal cells as well as formation of hyaline thrombi in small vessels in lung and other organs. 8, 10 In our case, however, we did not find evidence of vascular occlusion but instead a predominantly neutrophilic smallvessel vasculitis, suggesting that the pathogenesis of the lesions may be different.
To our knowledge, this is the first clinical and histopathological report of COVID-19 infectioninduced acro-ischemic lesions. Similar to other reports 5 , our case also suggests that these acute and Accepted Article
