A 70-year-old man is seen at your office for multiple raised pigmented lesions over his back and chest. These have developed gradually over several years. There are two lesions on the mid-lower back that intermittently itch intensely and are somewhat larger and much darker than the other lesions, which number 50 or more.

5. If you determine that one or both of the darker lesions are seborrheic keratoses, how should you treat them?
