Seborrheic Keratosis

Seborrheic keratosis, sometimes called an SK or age spot, is a growth that develops on skin with age. A seborrheic keratosis can be skin colored, tan, gray or brown to black, and is raised. Typically they are located on the face, chest, shoulders, back and legs.

It is a benign (noncancerous) growth that can appear stuck on, wart-like and can also look waxy. The size of a seborrheic keratosis can be anywhere from a small dot to as large as a dollar-size pancake, but most are typically the size of a pencil-eraser to a dime. They can be round or oval and it is not uncommon for people to have clusters of growths.

While seborrheic keratoses are not dangerous, many people feel that they affect their appearance and choose to have them removed. Treatment options include surgery, cryotherapy (freezing), and new topical options.
