Generalized pustular psoriasis‐like widespread eruption following COVID‐19 infection in a patient with spondyloarthropathy on adalimumab

Abstract

AbstractGeneralized pustular psoriasis (GPP) is a form of pustular psoriasis that is distinguished by recurring or persistent outbreaks of non‐acral primary sterile pustules. These eruptions can occur with or without systemic inflammation. Various factors, such as medications, stress and viral infection, have been identified as potential triggers for GPP flares. While several cases have detailed GPP‐like eruptions in the setting of coronavirus disease 2019 (COVID‐19) infection, few have explored the interplay between infection and biologic use in the development of GPP. In this case, we detail the history and management of a 45‐year‐old male patient with a prior history of spondyloarthropathy managed on a tumour necrosis factor‐α inhibitor and recent COVID‐19 infection presenting with a new, spreading pustular rash.
