Psoriasis is a common immune-mediated, inflammatory skin disease. However, unilateral psoriasis is rare and few cases have been reported. A 59-year-old male with a polio-affected right leg presented with exfoliative skin on the left leg for three months. He had been treated under the diagnosis of contact dermatitis with secondary infection. After the exfoliative skin lesions improved, psoriatic papules were noted, which was ultimately diagnosed as psoriasis and successfully treated with topical steroid and vitamin D agents. We propose that the Koebner phenomenon has acted as the triggering and aggravating factor of unilateral psoriasis in this patient.
银屑病是一种常见的免疫介导性炎症性皮肤病。然而，单侧银屑病较为罕见，仅有少数病例报道。一名59岁男性，右腿因小儿麻痹症致残，左腿出现皮肤脱屑三个月。他曾被诊断为接触性皮炎伴继发感染并接受治疗。在脱屑性皮肤病变改善后，发现了银屑病丘疹，最终被诊断为银屑病，并通过外用类固醇和维生素D制剂成功治愈。我们认为，同形反应是该患者单侧银屑病的触发和加重因素。
