Can café-au-lait spots suddenly appear in adulthood?

Yes. Café-au-lait (CAL) spots are most often present on a newborn’s skin but it is common for CAL spots to develop on a person’s skin later in life. It is normal for a person to have a few CAL spots but more than six spots may be a sign of an underlying condition. No matter what age, if you notice you have more than six CAL spots on your body, contact your healthcare provider to examine your spots for an underlying condition.
