Seborrheic Keratoses (SKs) are very common benign skin lesions.
Over 90% of adults over the age of sixty have at least one, though most people have numerous lesions.
They occur in males and females of all races, and typically start occurring in the 30s and 40s. They are rare under the age of twenty. They appear as harmless warty, rough growths in most cases, but can also appear smooth and waxy.
They are also known as the “barnacles” of the skin.
- A person’s tendency to develop them is genetically related.
- People who have family members with numerous lesions tend to develop more lesions.
- These lesions are benign despite their often varied and asymmetric appearance.
- They can also itch, bleed, or become irritated from rubbing against clothing.
Seborrheic Keratoses can be treated in the office with liquid nitrogen.
Additionally, it is important not to dismiss lesions as SKs in some cases, since they can easily be confused with moles or nevi, and it is important not to ignore an atypical mole.
Thus, we encourage everyone to schedule an appointment for an annual skin check to make sure that we can identify true nevi from these benign SKs.
