Hi everyone! Today I want to discuss several benign skin lesions that appear on many people that can often look like skin cancers. These are the growths that bring many people into the dermatologist's office as they can mimic the appearance of all types of skin cancer. Fortunately, these benign lesions are much more common than the skin cancers! A very common growth is called a "seborrheic keratosis" and is related to age as they tend to appear after 30 years ofage. They tend to be rough and can range from being flesh colored to black. These skin growths tend to cause itching or irritation and can grow very quickly. Many people have multiple lesions and some people refer to these as "age spots" or "barnacles." If peeled off, they tend to grow back, and this frustrates many people! Fortunately, these are completely benign and have no cancerous potential.

Editorial review provided by VeriMed Healthcare Network on April 18, 2005. Wrinkles are the thin, creased, and sagging skin that is especially noticeable on the face, neck, and hands. Wind, heat and chemicals and the natural effects of aging cause a certain amount of wrinkling in everyone, but it is much worse in people who spend a lot of time in the sun. Years of exposure to the sun cause "photoaging," which includes freckles, yellowing, roughness, visible blood vessels, and dark spots, as well as wrinkling. Years of sun exposure cause the supporting structures of the skin, primarily the collagen and elastin, to weaken and break down. In addition, as a person ages, the sweat and oil glands of the skin become less numerous and smaller in size. This causes the skin to lose moisture and to dry out. Dry skin with weak collagen and elastin will...
