The mean age at onset of GPP was 40.9 years (range: 21–81 years). Acute GPP was the most common variant seen (95 cases), followed by four localized variants of GPP and three with annular pustular psoriasis. Fever and painful skin were present in 89% of patients, arthritis in 34.7%, and leukocytosis in 78.4%. Common triggers were systemic steroids (45 cases), pregnancy (17 cases), and upper respiratory tract infections (16 cases). A positive family history of psoriasis and GPP was present in 29% and 11%, respectively. Comorbidities included obesity (42.9%), hypertension (25.7%), hyperlipidemia (25.7%), and diabetes mellitus (23.7%). The mean duration of admission and pustular flare for acute GPP was 10.3 days (range: 3–44 days) and 16 days (range: 7–60 days), respectively. Fifty‐four patients responded to systemic retinoid, 21 to methotrexate, eight to cyclosporine, and one to adalimumab, but recurrences were common.</p> </sec> <sec id="ijd12070-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Our study confirms the poor response of GPP to currently available anti‐psoriatic agents, with frequent flare‐ups. There is a need for a more effective targeted therapy for this condition.</p> </sec> </abstract>
