Precancerous Skin Conditions Actinic (Solar) Keratosis. Actinic keratosis (also called solar keratosis) is a skin lesion caused by too much sun exposure. There is some increased risk of skin cancer in patients who have these lesions, but the risk of one specific actinic keratosis turning into cancer is low. The increased risk of cancers may be due to the fact that heavy sun exposure has been linked to both actinic keratosis and nonmelanoma skin cancers. Actinic keratosis occur after years of sun exposure. They appear mostly on sun-exposed skin, such as the face, neck, back of the hands and forearms, upper chest, and upper back. Men may develop keratosis along the rim of the ear. Actinic keratosis have the following characteristics: Lesions typically occur on the surface of the skin and have a sandpaper-like feel. In fact, they are sometimes more easily felt than seen. Most lesions are pink and even flesh-colored. Some are red or brown, scaly, and tender. At times, they can resemble melanom...
Do you ever get the sensation of itching all over your body? I had it so bad last week that I could barely sleep. I kept waking up to scratch my back and legs, and was convinced I had bed bugs. As I developed an outbreak over the next few days, I began to wonder if the itching had anything to do with herpes. Like maybe it’s a form or neuralgia, with itchiness instead of pain. Since herpes lives in the nervous system, why wouldn’t it cause itchy sensations in other parts of my body, besides down below?
When I looked online to see if there was any connection between herpes and general bodily itching, I did find several others who were concerned about the same thing. Though others reassured them that there was no correlation between herpes and random skin itching, I did find it interesting that there was some discussion about it already. I thought maybe some of you who frequent this site might have the same concerns and some i...
Did you know the largest internal organ of the body is the liver? But the overall largest organ of the body is the skin. It’s no wonder the skin is involved with so many aspects of diseases: rash, itching, fever, external bleeding, swelling, pallor (turning pale), and cyanosis (turning blue). Doctors look for signs of hundreds of diseases by examining the organ that is most accessible, the skin.
Often the skin is our first line of defense against adverse conditions such as hot and cold temperatures, external trauma (for example falling on hard ground) and harmful rays of the sun. We are protected from a myriad of germs (bacteria, viruses, fungi and parasites) by having a finely woven coat of armor, our skin.
Unfortunately certain substances, after contacting the skin, may cause a break down in protective barrier forces. This may be followed by inflammation and a skin eruption (rash) that signals the development of contact dermatitis (CD) .
