Seborrheic Keratoses

What Are Seborrheic Keratoses?

Seborrheic keratoses are very common benign growth that occurs on the skin as people age. The exact cause of these are unknown, but they are often hereditary. Most frequently, they occur on the face, chest and back. They can have various shades of tan, brown or even black, so they can be mistaken as moles. These lesions can grow to be large and thick, or cause irritation.
