Currently, the pathogenesis of linear psoriasis is not fully understood, and genetic mosaicism may be one of the explanations. As linear psoriasis is less responsive to treatment than psoriasis vulgaris, there is no consensus on treatment guidelines specifically for this disease, and the efficacy of ustekinumab in treating this category has not been reported. In this article, we present a case of effective treatment of linear psoriasis with ustekinumab and review the relevant literature, hoping to help clinicians better understand and treat this disease.<\/jats:p>","DOI":"10.3389\/fimmu.2025.1553793","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T05:26:25Z","timestamp":1745299585000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Ustekinumab
