Verrucoid keratosis simply means superficial skin lesions (keratoses) that appear wart-like (verrucoid). These frequently develop in middle age, are usually benign, and are not contagious.

Can you tell me waht causes them?
Expert:  A. Schuyler, NP replied 9 years ago.
You're very welcome. Nobody really knows what causes them, but they seem to be degenerative in nature since they occur over 50. They aren't caused by sun exposure since people can get them both on exposed areas and places the sun never shines. They tend to increase in number as one ages. Some of them can be confused with skin cancers, so everyone should have their keratoses looked at when they have their yearly physical just to make sure they are the innocent keratoses.
