About Seborrheic Keratoses

Seborrheic keratoses (SKs) are non-cancerous skin growths that are most commonly seen in middle-aged and older adults. SKs vary in color from flesh-colored to pink, yellow, gray, tan, brown, or black; can range in size from a millimeter to a few centimeters wide; and typically have a slightly elevated, waxy or scaly appearance. The number of SKs tends to increase with advancing age. SKs frequently appear in highly visible locations, such as the face or neck, but can also appear anywhere on the body, except the palms, soles and mucous membranes.
