Psoriasis is a chronic, inflammatory skin disorder characterized by well-demarcated erythematous-scaly lesions, affecting 0-6.6% of the world population. Facial lesions are neglected in most descriptions in current literature, although some studies indicate that it could be a predictor of psoriasis severity.
To compare the severity of psoriasis, measured by the Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI), in patients with and without facial lesions.
This is a cross-sectional study, whose sample size was 63 individuals for each group. Subjects were included in the HUPES Complex Dermatology Service (Salvador/BA - Brazil) from April 2014 to January 2016. Demographic information was obtained using a prestructured form. Assessments of psoriasis severity and quality of life were done using PASI and DLQI, respectively.
Facial lesions were detected on 63 (50.0%) of the 126 patients included. The pinna was the most frequently affected region (63.5%). Mean PASI in the group with facial involvement was 14.0 vs. 6.0, when facial involvement was absent. DLQI means for these groups were, respectively, 7.5 and 4.7.
Facial involvement in a psoriasis patient was a marker of disease severity, and its identification should influence the therapeutic decision.
银屑病是一种慢性炎症性皮肤病，其特征为边界清楚的红斑鳞屑性皮损，影响全球 0-6.6%的人口。目前的文献中大多数描述都忽略了面部皮损，但一些研究表明，它可能是银屑病严重程度的一个预测指标。
比较面部皮损存在和不存在的银屑病患者的银屑病严重程度（用银屑病面积和严重程度指数[PASI]和皮肤病生活质量指数[DLQI]衡量）。
这是一项横断面研究，每组的样本量为 63 人。2014 年 4 月至 2016 年 1 月期间，研究对象纳入 HUPES 综合皮肤科服务（巴西萨尔瓦多）。使用预结构化表格获取人口统计学信息。使用 PASI 和 DLQI 分别评估银屑病严重程度和生活质量。
在纳入的 126 例患者中，有 63 例（50.0%）存在面部皮损。耳廓是最常受累的部位（63.5%）。有面部受累的患者的平均 PASI 为 14.0，而无面部受累的患者为 6.0。这些患者的 DLQI 平均值分别为 7.5 和 4.7。
银屑病患者存在面部皮损是疾病严重程度的标志，其识别应影响治疗决策。
