Diversity in the clinical presentation of generalized pustular psoriasis (GPP): A series of case vignettes from around the world

Abstract

A key principle of clinical studies and case reports is that they should reflect the demographics and epidemiology of the patient population concerned. Here, we have compiled a diverse group of clinical cases of generalized pustular psoriasis (GPP) to showcase the differences in GPP presentation in patients worldwide. We attempt to capture the broad spectrum of clinical presentations of GPP and showcase the diversity of the patient population. The patients included in this series are diverse in age, genetic background, skin phototype and medical history. Moreover, they present with a variety of clinical courses of GPP and different degrees of systemic involvement, and experience flares triggered by different inciting factors. The key learnings from this case series may support physicians in identifying and managing patients with this rare and multifaceted disease that can affect patients both physically and psychologically.

Acquired diffuse palmoplantar erythema with keratoderma in Chinese patients with pustular psoriasis: A predictor for IL36 receptor antagonist c.115+6T>C mutation?

“…There are significant diversity in the clinical presentation and genetic background of GPP. 15 disease manifestation and treatment response. Null IL36RN mutations were associated with GPP, while patients with hypomorphic IL36RN mutations were more likely to develop localized forms of pustular psoriasis.…”
