Seborrheic keratoses: Signs and symptoms
What are the signs of seborrheic keratoses?
Seborrheic keratoses tend to:
Start as small, rough bumps, then slowly thicken and develop a warty surface
Have a waxy, stuck-on-the-skin look
Be brown, though they range in color from white to black
Range in size from a fraction of an inch to larger than a half-dollar
Form on the chest, back, stomach, scalp, face, neck, or other parts of the body (but not on the palms and soles)
Cause no pain, though some itch
Seborrheic keratoses can look like stucco splattered on the skin.
Like his father, this man developed many of these growths on his skin.
