Objective To investigate the pattern of distribution of geriatric dermatoses and its clinical charac-teristics for the elderly .Methods A total of 1 094 patients who were 60 years old or older admitted at the department of dermatology and venereology in the First Affiliated Hospital of Chongqing Medical University from Jan .2011 to Apr .2013 were all included in this retrospetive study .The distribution and the clinical characteristics of disease were compared with those of 715 middle adulthood patients from 45 to 59 years old .Results Among 1 094 elderly pa-tients ,the top three kinds of skin disease were allergic skin diseases (334 cases ,accounting for 30 .53% ) ,virus infec-tious skin disease(241 cases ,accounting for 22 .03% ) ,skin malignant tumor(87 cases ,accounting for 7 .95% ) .The male to female patients ratio was 1 .42 ∶ 1 ,and the ratio was increased with age .There were significant differences on the incidences of eczema ,psoriasis ,urticaria between elder patients and middle adulthood patients (P < 0 .05) .In the elder patients ,the incidence of herpes zoster had a significant sex difference (P< 0 .05) .In the middle adulthood pa-tients ,the incidence of erysipelas had a significant sex difference(P< 0 .05) .Conclusion Skin diseases in the elderly were not uncommon ,there were relationships between the pattern of distribution of skin diseases and gender ,age ,im-munity ,multiple basis chronic diseases .%目的：调查皮肤性病科老年住院患者的患病情况及病种的构成比例。方法对重庆医科大学附属第一医院2011年1月至2013年4月皮肤性病科住院年龄大于或等于60岁的老年患者1094例进行回顾性分析，并将其患病情况及病种分布情况与45～60岁的中年患者进行比较。结果老年组皮肤病共21类58种，其中前三类的是变态反应性皮肤病334例，占30．53％；病毒感染性皮肤病241例，占22．03％；皮肤恶性肿瘤87例，占7．95％。老年男性皮肤病患者稍高于女性患者（男∶女＝1．42∶1），且随着年龄的增长，男女比逐渐增大（60～69岁为1．20∶1；70～79岁为1．58∶1；≥80岁为1．70∶1）。湿疹、银屑病、荨麻疹在老年组与中年组间比较，差异有统计学意义（P＜0．05）；而带状疱疹仅在老年组不同性别间比较，差异有统计学意义（P＜0．05）；丹毒仅在中年组不同性别间比较，差异有统计学意义（P＜0．05）。结论皮肤病在老年患者中并不少见，其病种构成与多种因素相关，以性别、年龄、自身免疫力、并发的多种基础或慢性疾病影响较大。
