II. Seborrheic Keratoses Causes
The tendency to develop
seborrheic keratoses is inherited.
Seborrheic keratoses are harmless and almost never become malignant.
Seborrheic keratoses
begin as slightly raised, light brown spots. Gradually they thicken and take
on a rough, wartlike
surface. They slowly darken and may turn black. These
color changes are harmless.
Seborrheic keratoses are superficial and look as if they were stuck on the skin.
