Seborrheic Keratoses

Seborrheic keratoses (SKs) are benign, common skin growths that typically appear in adults older the age of 30 years. They are inherited genetically and typically increase in number on the skin with time. Seborrheic keratoses can appear dark and concerning but are harmless and will not progress into any type of skin cancer.

These lesions begin as slightly raised, flesh-colored or light brown spots. Gradually, they thicken and take on a rough, wart-like surface. Some can become irritable and inflamed, especially if located in an area of friction. Most seborrheic keratoses darken with time and can turn black. These color changes do not indicate malignancy; however, if you are concerned about any growth, consult your provider.

Treatment

Seborrheic keratoses can easily be removed in the office through cryosurgery (freezing with liquid nitrogen).  These lesions are typically only removed if they are irritated and/or symptomatic.
