Skin can show first signs of some internal diseases

Dermatologists find that the skin offers a window to what is going on inside the body, and changes to the skin may signal a more serious health problem. The key is knowing how to spot these early warning signs so the internal disease can be successfully treated and before it becomes a bigger problem. In some cases, the skin can show signs of an internal disease before the disease advances and becomes more serious; in other cases, a symptom is noticeable on the skin long after the disease begins causing damage internally. There are hundreds of nuances of the skin that could spell trouble, but a handful of general skin changes commonly signal an internal disease. http://www.aad.org/stories-and-news/news-releases/skin-can-show-first-signs-of-some-internal-diseases--
