Generalized 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.

This article, published in Experimental Dermatology, explores the prevalence of anemia as a comorbidity in patients with pyoderma gangrenosum (PG), a rare inflammatory skin disease. The study analyzed data from the National Inpatient Sample (NIS) database, which includes information on hospitalizations in the United States. The researchers found that patients with PG and anemia had longer hospital stays and higher costs of inpatient care compared to those without anemia. However, these differences were not significant after controlling for demographic factors and other comorbidities. The study suggests that further research is needed to understand the relationship between anemia and PG. [Extracted from the article]
