Can people have birthmarks on their tongue?

Yes, people can have birthmarks on their tongue. Tongue birthmarks are relatively rare and are usually present from birth. They may appear as small, flat, or raised spots on the tongue and can range in color from red to black. Although tongue birthmarks are usually harmless, some may be associated with certain medical conditions, such as Down syndrome or Beckwith-Wiedemann syndrome. In rare cases, tongue birthmarks may also indicate an underlying medical condition, such as an oral cavity cancer, and should be evaluated by a healthcare professional if they change in size, shape, or color.
