One hundred and seven psoriatics with palmoplantar involvement were clinically examined. They were selected from 921 patients filed in 1976 with the diagnosis psoriasis. Fifty per cent of the patients with palmoplantar psoriasis had flexural changes. The frequency of palmar involvement in patients with inverse psoriasis compared to patients with psoriasis vulgaris was increased 5.3 times. Pustulosis palmoplantaris (PPP) in addition to psoriasis was diagnosed in 18 patients (17%). A dermatophyte infection was observed in 1 of 48 patients examined for tinea infection. Positive patch tests were obtained in 8 of 47 patients, 7 of whom had more than one test reaction. The result gives no evidence of tinea infection and contact allergy as important factors in maintaining palmoplantar psoriasis.
对107例有掌跖受累的银屑病患者进行了临床检查。他们是从1976年存档的921例诊断为银屑病的患者中挑选出来的。掌跖部银屑病患者中有50%有屈侧改变。反向银屑病患者掌部受累的频率与寻常型银屑病患者相比增加了5.3倍。除银屑病外，18例患者（17%）被诊断为掌跖脓疱病（PPP）。在48例接受癣感染检查的患者中，有1例观察到皮肤癣菌感染。47例患者中有8例斑贴试验呈阳性，其中7例有不止一种试验反应。结果没有证据表明癣感染和接触性过敏是维持掌跖部银屑病的重要因素。
