Nails, particularly fingernails, may show signs that are important not only for detection of diseases of the nails themselves, but of diseases of other organs or the system as a whole. Changes of color in nail plates or nail beds sometimes seem to suggest the parts are windows to what is happening in the body. Above all, changes of color in nails that compel investigation for malignant melanoma, the most dread of diseases, are most important.
指甲，尤其是手指甲，可能会显示出一些迹象，这些迹象不仅对于指甲自身疾病的检测很重要，对于其他器官或整个系统的疾病检测也很重要。指甲板或甲床的颜色变化有时似乎表明这些部位是身体内部状况的窗口。最重要的是，指甲颜色的变化促使人们对恶性黑色素瘤进行调查，恶性黑色素瘤是最可怕的疾病，这一点最为重要。
