Seborrheic Keratoses

Seborrheic keratoses (SKs) are common, benign skin growths that appear as rough and scaly or smooth and waxy, slightly raised patches on the skin. They are most commonly found on the face, chest, and back and have a waxy, "stuck-on" appearance. They range in color from light tan to dark brown and are often mistaken for warts or moles.

The exact cause of seborrheic keratoses is not known, but they are more common as people age. They are not dangerous, but they can be irritating or cosmetically bothersome. Treatment options for seborrheic keratoses include observation, cryotherapy (freezing), electrocautery (burning), and removal by shave technique. It is important to see a dermatologist if you have any concerns about seborrheic keratoses.
