SARS‐CoV‐2 endothelial infection causes COVID‐19 chilblains: histopathological, immunohistochemical and ultraestructural study of 7 paediatric cases	2020-06-20		.txt	text/plain	2530	162	43	title: SARS‐CoV‐2 endothelial infection causes COVID‐19 chilblains: histopathological, immunohistochemical and ultraestructural study of 7 paediatric cases CONCLUSIONS: Although the clinical and histopathological features were similar to other forms of chilblains, the presence of viral particles in the endothelium and the histological evidence of vascular damage, support a causal relation of the lesions with SARS‐CoV‐2. 4 Most patients have been negative for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) when tested by PCR of nasopharyngeal and oropharyngeal swabs, and less than 50% have a history of exposure to positive household contacts or previous history of mild upper respiratory or gastrointestinal symptoms. Lymphocytic vascular damage was the hallmark feature in biopsies from our 7 patients with COVID-19 related chilblains. 25 We have demonstrated the presence of viral particles within endothelial cells in lesional skin biopsies from patients presenting with chilblains during the COVID-19 pandemic.
