What is seborrheic keratosis?

Seborrheic keratoses are common, non-cancerous, skin lesions that are often found on the skin of older patients. Seborrheic keratoses (also known as SKs) are often not bothersome at all, however, sometimes they can be itchy or irritating from rubbing on clothing.

What causes seborrheic keratosis?

If you have a lot of seborrheic keratoses, you may have inherited them from your parents. The good news is, seborrheic keratoses are non-cancerous skin lesions and are typically not harmful to your health.

How is seborrheic keratosis treated?

Seborrheic keratoses are non-cancerous skin lesions that do not require treatment. However, if they itch or irritate you, you may choose to have them treated. Seborrheic keratoses are typically treated in the office using liquid nitrogen. They can also be removed via shave biopsy. Think you may have seborrheic keratoses and have questions about them?
