Treating elderly patients has become common in daily clinical practice. Consequently, it is important to focus our interest on a neglected region: the nail area. Anatomy and physiology are indispensable for a good comprehension of some phenomenons. Histopathology of senile changes may explain some pathologic situations and is indispensable for diagnosing uncommon tumors. Chemical composition shows that a normal nail contains 18% water. The rate of linear nail decreases as age advances. Ridging is a normal finding on fingernails, with color varying from shades of yellow to grey. The most common disorders, however, are linked to repeated trauma, with sometimes ingrowing toenails with different appearances. Tumors in the nail area are relatively frequent. Nail fungal infection may be isolated or associated with conditions such as psoriasis and diabetes. The management of the main nail disorders observed in the elderly are presented.
老年患者的治疗在日常临床实践中已较为常见。因此，关注一个被忽视的领域非常重要：指甲区域。解剖学和生理学对于理解某些现象至关重要。老年变化的组织病理学可以解释一些病理情况，并且对于诊断不常见的肿瘤也是必不可少的。化学成分表明，正常指甲含有 18%的水分。随着年龄的增长，指甲的线性生长速度会减慢。脊状隆起是指甲的正常现象，颜色从黄色到灰色不等。然而，最常见的疾病与反复创伤有关，有时会出现不同外观的嵌甲。指甲区域的肿瘤相对常见。指甲真菌感染可能是孤立的，也可能与银屑病和糖尿病等疾病相关。本文介绍了老年人中观察到的主要指甲疾病的治疗方法。
