Benign Keratosis - Causes, Symptoms & Treatment

Benign keratoses allternartive name is seborrheic keratoses. Seborrheic Keratoses (SK) is a skin lesion. tend to be most common on sun-exposed areas in older patients. Some patients may have dozens of them, most commonly on the face, neck and trunk. They have no malignant potential. Because they are very superficial lesions, they can be removed by a variety of methods with little or no scarring. Seborrheic keratosis is a benign form of skin tumor. It commonly appears after age 40. They often appear on the back or chest but are also common on the scalp, face, arms, and legs. Seborrheic keratoses grow slowly, in groups or singly. Most people will develop at least one seborrheic keratosis during their lifetime. The tumors appear as wart-like growths in a variety of colors. They may appear in large numbers on the surface of the body. They are usually painless and benign, but may become irritated and itch. They may be cosmetically disfiguring and psychologically distressing as a result.

The most common causes of benign keratosis is Sun exposure. They are increasingly common in the later decades of life. Children seldom develop these skin growths. Seborrheic keratoses primarily affect people older than 30. Some women notice that they develop them during pregnancy or after taking estrogen. Some patients may have dozens of them, most commonly on the face, neck and trunk. Typically, SKs have sharp borders, a tan-brown-black color, a "glued-on" appearance, and may be crusty, warty, or occasionally smooth. Occasionally, the surface may crumble, especially when they are picked or irritated , they may ooze and bleed. Irritated or irregularly shaped SKs may be mistaken for skin cancer or melanoma

Common Treatment of Benign Keratosis

  • Cryosurgery is liquid nitrogen, a very cold liquid gas, is applied to the growth with a cotton swab or spray gun to “freeze” it. A blister may form under the growth which dries into a scab-like crust. The keratosis usually falls off within a few weeks.
  • Electrosurgery — the growth is anesthetized (numbed) and an electric current is used to burn the growth.
  • Avoid deliberate tanning.
  • Wear long sleeves, pants, a wide-brimmed hat, and sunglasses that protect against both UVA and UVB rays.
  • Use extra caution near water, snow, and sand.
  • Injection and spray is first used to anesthetize (numb) the area before the growth is removed (curetted).
