Seborrheic keratoses (also known as warty keratoses) are benign, rough, scaly often “warty” entirely harmless growths on the skin, which almost everyone gets, as one grows older. They can appear almost anywhere on the body. They are a thickening of the top layer of the skin, and unlike true moles (nevi), they have no roots. They are often found in areas NOT exposed to the sun and range in color from skin-color to tan, to brown, to dark brown, to jet-black. They may be pinhead in size to 2-3 inches in diameter. Unlike true moles, they do not contain mole cells, and therefore never turn into cancer. Since they are superficial they can often be scraped off, and pieces often come off as people towel themselves dry after bathing. Since they can stick up, they are often irritated and can itch, bleed, change color, become red and inflamed or even fall off by themselves. This is never a sign of cancer.

Some people have a few of these but others may have dozens! This depends on genetics. They are found in all races and although they are more prevalent with age, younger individuals can get them, too. They are not warts and are not caused by a virus or a germ.

Seborrheic keratoses are purely a cosmetic problem and there is rarely a medical reason to treat them. There are exceptions, of course, such as severe irritation.

TREATMENT: There is no way to prevent these from coming. Nor is there anything that you can put on them to make them disappear. All methods of treatment involve some form of destruction, but they may recur and you will get more of them. They can be scraped off, or frozen with liquid nitrogen. All treatment methods involve some degree of discomfort, mostly minimal for the average person.

Please be aware that your medical insurance may not cover treatment because it is considered cosmetic. This is especially true of medicare.
