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

“…real-time reverse transcriptase polymerase chain reaction (rRT-PCR) testing were variable. [1][2][3] Recalcati et al 2 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.…”

“…Most of dermatological manifestations during the COVID-19 involved the cutaneous microvascular system with acral eruption with possible bullous evolution, chilblain-like lesions, transient livido reticularis and acrocyanosis. [1][2][3]5 Because endothelial cells express ACE2, a receptor for SARS-CoV-2, microvascular lesion is consistent with pathophysiology of COVID-19. While evidence of SARS-CoV-2 in the lung during the acute phase has been provided through electron microscope, immunohistochemical staining and rRT-PCR, only inflammatory lesions were found in other organs and tissues.…”

Cutaneous signs in COVID ‐19 patients: A review

“…In a WhatsApp group of French dermatologists, 295 cases with cutaneous manifestations were collected. The most common cutaneous finding was chilblain‐like eruption with 146 posts 19 . Most of the contributors were dermatologists in private practice with milder cases of possible COVID‐19 disease.…”
