What are seborrheic keratoses?

Dr. Mehmet Oz, MD

Seborrheic keratoses are noncancerous skin growths that are usually brown, but they can range in color from black to white. Unlike moles, seborrheic keratoses rarely occur in childhood but are most likely to appear on the skin in middle and older age. They can appear anywhere on the skin, except for the soles of the feet and the palms of the hands, according to the American Academy of Dermatology. If you have concerns about seborrheic keratoses, talk to your dermatologist for more information.

This benign lesion is a dry, raised, wart-like growth that appears on the skin seemingly overnight and out of nowhere. It is easily mistaken for a scab that forms over a pimple that's healing, but this one won't go away. The growth is created when too many dead keratinocytes get rolled up like an onion into a scaly little mass, which is why it looks and feels like a hard clay blob. Seborrheic keratoses (SK) have been dubbed "keratin pearls," but they're stuck onto the skin more like a barnacle.
