It measures 16 mm × 8 mm. She has approximately 20 nevi that appear normal. The patient reports never performing self-skin examinations and does not know if the lesion in question is new. She denies any symptomatic lesions. Her family history is remarkable for "skin cancer" on her father's side. Many family members have "tons of moles." She frequented a tanning parlor in college (too much free time … probably majored in communications) and occasionally still does so before social events (didn't learn much about skin health in college).
