Kershaw,
Hyperkeratosis is exactly as Cookey described it.
It can grow and become larger but usually only in response to a local irritant, trauma, and or chemical.
Actinic Keratosis can be a premalignant condition, but generally hyperkeratosis is a benign condition that will go away when the causitive agent is eliminated.

Hope this is of some use to you.
