Seborrheic Keratosis

Also known as seborrheic verruca, most people will develop at least one seborrheic keratosis during a lifetime. Fortunately, these lesions are benign and don’t become cancerous. Seborrheic keratoses usually show up in older adults and appear as black, brown, or pale growths on the back, chest, face, or shoulders. Although seborrheic keratoses can appear by themselves, usually more than one growth develops.


Generally, seborrheic keratosis requires no treatment. Patients often choose to remove the benign growths if they bleed, become irritated or look unsightly. Insurance does not usually cover the removal of seborrheic keratosis when it is for cosmetic reasons only. Because seborrheic keratoses do not develop deep roots, removal is easy and does not usually leave scars.

To remove the seborrheic keratosis, your doctor can:

  • Freeze the growth with liquid nitrogen
  • Scrape the area with curettage
  • Burn the spot with an electric current
