Chilblain-like acral lesions during the COVID-19 pandemic ("COVID toes"): Histologic, immunofluorescence, and immunohistochemical study of 17 cases.
During the coronavirus disease 2019 pandemic, several acral chilblain-like lesions were observed in young patients with suspected, but mostly unconfirmed, infection with severe acute respiratory syndrome coronavirus 2. The histopathologic aspect of these lesions is as yet poorly known. ⋯ Chilblain-like lesions show histopathologic features similar to those of idiopathic and autoimmune-related chilblains, with a high rate of vascular changes and direct immunofluorescence positivity. The role of severe acute respiratory syndrome coronavirus 2 in the development of these puzzling lesions remains to be elucidated.
