Seborrheic Keratosis

Exams and Tests

Your doctor can diagnose most seborrheic keratoses by doing a visual exam. He or she will look for the common appearance of a rough and bumpy surface.³ You may need a skin biopsy to rule out cancer if you have growths that:

• Itch or bleed.
• Become inflamed and red.
• Are dark brown to black.
