New-onset pustular psoriasis in the setting of severe acute respiratory syndrome coronavirus 2 infection causing coronavirus disease 2019

National Psoriasis Foundation COVID-19 Task Force guidance for management of psoriatic disease during the pandemic: Version 2—Advances in psoriatic disease management, COVID-19 vaccines, and COVID-19 treatments

“…Patients with psoriatic disease should be aware that infection with SARS-CoV-2 may result in a flare of psoriasis, including pustular flares (guidance 5.6). [74][75][76][77][78][79][80][81] Patients with psoriatic disease who become infected with SARS-CoV-2 should follow Centers for Disease Control and Prevention guidance on home isolation and discuss with their health care providers when they can end home isolation (guidance 5.7; Version 1, Supplemental Table IX available via Mendeley at https://doi.org/10.17632/w5m8jf94m8. 2).…”

Acrodermatitis Continua of Hallopeau Evolving into Generalized Pustular Psoriasis Following COVID‐19: A Case Report of a Successful Treatment with Infliximab in Combination with Acitretin

“… 35 A recently published case report of a 62-year-old-woman with a positive family history for psoriasis differed from the aforementioned ones as the described patient developed a new-onset PP two weeks after the resolution of SARS‐CoV-2 infection symptoms. 36 In November 2020, another case of PP exacerbation secondary to COVID-19 was published. The described patient was also treated with hydroxychloroquine, albeit unlike the previously reported cases, she had a history of hydroxychloroquine use without exacerbation of psoriasis; therefore, the authors concluded that SARS‐CoV-2 alone might have led to the PP flare-up.…”

New-onset guttate psoriasis secondary to COVID-19

“…That was the first and the only case of new-onset psoriasis induced by COVID-19 described in the literature. The delay was explained by the fact that SARS-CoV-2 related inflammation has not yet resolved even though the patient was asymptomatic 5 . A dysregulation of innate immune response due to stimulation of toll-like receptor 3 by viral RNA leading to production of pathogenic cytokines (IL17, IL23) might be a possible mechanism for COVID 19 infection leading to psoriasis 2 .…”
