A retrospective chart review of 332 pediatric psoriasis patients seen at a single academic institution from 2012 to 2022 was conducted to examine the risk factors associated with palmoplantar psoriasis (PP), a painful and treatment-resistant subtype of plaque psoriasis affecting hands and feet. Black patients have a 6.386-fold increase in the odds of having PP compared to White patients and males have a 2.241-fold increase in the odds of having PP. Black and Hispanic/Latino patients displayed a higher prevalence of nail and palm/sole involvement (p < .0001), whereas White patients exhibited more scalp involvement (p = .04). This study reveals the importance of considering the diagnosis of PP in Black male patients based on its demographic prevalence, which may in turn impact clinical care for these patients.
