Skin diseases. Acne. Lupus. Skin cancer. Rebeola. Hemngioma of skin. Cold sore. Skin cancer. Skin Cancer is the uncontrolled growth of cancer cells in the skin. Left untreated, these cells can spread to other organs and tissues, such as lymph nodes and bone. Skin cancer is the most common cancer in the United States, affecting one in five Americans during their lifetimes. Lupus. Lupus is an autoimmune disease that affects more than 1.5 million Americans, according to the Lupus Foundation of America. Normally, the immune system protects the body against foreign invaders like viruses and bacteria. In the case of a disease like lupus, the immune system mistakenly attacks the body and damages healthy tissues and organs. Lupus can cause problems with the kidneys, nervous system, blood vessels, and skin. Hemangioma of Skin Hemangiomas are noncancerous growths that form due to an abnormal collection of blood vessels. They are usually found on the skin or internal organs—particularly the liver. Because they are congenital, most people develop them before birth, while they are still in the womb. Rebeola. Rubeola (measles) is an infection caused by a virus that grows in the cells lining the throat and lungs. It’s a very contagious disease that spreads through the air whenever someone who is infected coughs or sneezes. People who catch the measles develop symptoms like a fever, cough, runny nose, and the tell-tale rash that is the hallmark of the disease. If measles isn’t treated, it can lead to complications like ear infection, pneumonia, and encephalitis (inflammation of the brain). Acne. Your skin has tiny holes called pores that that can become blocked by oil, bacteria, and dirt. When this occurs, you may develop a pimple or “zit.” If your skin is repeatedly affected by this condition, you may have acne. Cold sores. Cold sores are red, fluid-filled blisters that appear near the mouth or on other areas of the face. In rare cases, cold sores may appear on the fingers, nose, or inside the mouth. There is no cure for cold sores, and infections tend to reoccur without warning. Sores are contagious and may persist for more than one week.
