Abstract
Several articles recently reported a "varicella-like" rash in patients with COVID-19 [1,2]. We observed similar cases at our institution. However, although we agree that the clinical picture is original, we reject that "varicella-like" denomination since clinical presentation, as well as some histologic features that we wish to report here for the first time, make it clearly different from varicella. Three patients with a vesicular rash associated with COVID-19 (RT-PCR test on a nasopharyngeal swab specimen positive for SARS-CoV-2 ARN) were seen at our institution in April, 2020. A biopsy of a vesicle was performed in each. Multiple levels with H&E stain were done; the slides were reviewed independently by two pathologists; only concordant data were validated. A test for SARS-CoV-2 was performed on a vesicle in two patients, and a direct immunofluorescence test on perilesional skin in one.
Keywords: Covid-19; SARS-CoV-2; acantholysis; coronavirus; skin rash; varicella.
