Notes
Seborrheic Keratosis
Appearance:Waxy, brown-to-black growths that can look like they are "stuck on" the skin.
Texture:Can be scaly, warty, or smooth with a dull appearance.
Location:Can appear anywhere except the palms and soles of the feet.
Common Characteristics:Often appear after age 40 and can occur in multiple clusters.
Dermal Nevus
Appearance:A well-defined, often dome-shaped, elevated bump.
Texture:Can range from skin-colored to brown and may be soft to firm.
Location:Frequently seen on the head and neck.
Common Characteristics:Often looks like a raised mole with a more organized structure than a seborrheic keratosis.
How to Tell Them Apart
Appearance and feel:Seborrheic keratoses often have a distinct "stuck-on" appearance and a waxy, sometimes rough surface, whereas dermal nevi are typically smooth, dome-shaped bumps.
History:Seborrheic keratoses become more common with age, while dermal nevi are also common but have a different origin.
