Various cutaneous manifestations have been observed in patients with SARS-CoV-2 infection, yet exacerbations of psoriasis have been reported sporadically. Acrodermatitis continua of Hallopeau (ACH) is an uncommon, sterile pustular dermatosis involving one or more digits. In some rare cases, ACH may evolve into generalized pustular psoriasis (GPP), which is a severe, and potentially life-threatening, form of psoriasis that manifests itself with widespread eruptions of pustules. We describe the first case of a patient in whom ACH abruptly progressed into GPP during COVID-19. A combination of infliximab and acitretin was used allowing swift clinical improvement.Keywords: psoriasis, pustular psoriasis, biologics, biologic therapy, SARS-CoV-2, coronavirus
