Exploring the Clinical Features, Immunopathogenesis and Approach to Diagnosis for Generalized Pustular Psoriasis [Podcast]

Clin Cosmet Investig Dermatol. 2023 Jun 16;16:1553-1558. doi: 10.2147/CCID.S424073. eCollection 2023.ABSTRACTGeneralized pustular psoriasis is a rare presentation of psoriatic disease and is characterized by the acute onset of diffuse superficial pustules on the skin. These pustules can often coalesce, forming what's known as 'lakes of pus' that are most often seen on the trunk and on skin folds. GPP flares are often accompanied by systemic symptoms, including fever, malaise, and edema. The interleukin (IL)-36 pathway plays a central role in the development of GPP, although several other genes may be associated. The rarity of GPP makes its diagnosis challenging and it could be mistaken for an infectious condition or other types of pustular psoriasis, including unstable forms of plaque psoriasis that may present with pustules. Performing a thorough skin examination and obtaining a detailed history are vital to exclude these differential diagnoses. Incorrect or late diagnosis, inadequate or delayed treatment, and lack of specialist referrals may contribute to increased disease severity and can have a debilitating impact on patients' quality of life. In this podcast, two US-based dermatologists discuss the clinical characteristics of GPP, highlight the central role of IL-36 in immunopathogenesis, and share practical approaches to recognizing and diagnosing the disease.PMID:37351064 | PMC:PMC10282158 | DOI:10.2147/CCID.S424073
