No antibody response in acral cutaneous manifestations associated with COVID-19 ?

Skins symptoms during COVID-19 have been recently described but their relation to SARS-CoV-2 is unclear while results for real-time reverse transcriptase polymerase chain reaction (rRT-PCR) testing were variable. Recalcati et al. reported 14 cases of patients with skin symptoms consistent with previous described COVID-19 lesions but all the patients were tested negative. They asked for a serology to validate the hypothesis that these lesions are related to COVID-19.
