Guttate Psoriasis Following COVID-19 Infection.

Guttate psoriasis is a subgroup of psoriasis that most commonly presents as raindroplike, erythematous, silvery, scaly papules. Guttate psoriatic flares may follow rhinovirus or COVID-19 infection due to dysregulation of the innate immune response. We describe the case of a patient who experienced a moderate psoriatic flare 3 weeks after diagnosis of SARS-CoV-2 infection. We discuss the dysregulation of proinflammatory cytokines that we believe triggered this flare and the treatment regimen for our patient.
