New-onset pustular psoriasis in the setting of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causing Coronavirus Disease 2019 (COVID-19)

Abstract

Psoriasis is a chronic, immune-mediated disorder mainly affecting the skin and joints. Pathogenesis involves keratinocyte hyperproliferation, complex cytokine and interleukin interactions, polygenic predisposition, and known association with environmental triggers including infections, medications, trauma, and stress.1 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Coronavirus Disease 2019 (COVID-19), is associated not only with flares of psoriasis in patients with well-documented disease,2-4 but also with other cutaneous diseases.5-7 However, there have yet to be any reports showing new-onset psoriasis in patients with SARS-CoV-2 / COVID-19. We report such a case in a 62-year-old woman.
