Keratoses are growths with a rough scaly texture. This category includes precancerous actinic keratoses and benign seborrheic keratoses.
Actinic keratoses commonly occur in fair-skinned individuals in sun exposed areas like the forehead, nose, cheeks, ears, and hands. They tend to be pink in color and feel dry like sand paper. It is important that they are they are treated since they can evolve into squamous cell carcinomas.
Seborrheic keratoses occur in people of all skin types. They tend to be tan to dark brown in color and occur almost anywhere on the body. They can be confused with a melanoma when they are darker in color. Since they may be difficult to distinguish from a melanoma, individuals with any darker changing spot should be checked by their dermatologist.
