A cluster of dilated tiny blood vessels called capillaries that forms a lesion anywhere on the skin or mucous membranes.


Self-care options for skin lesions include using makeup or self-tanning lotion to hide marks. Sun-protection measures also may help.

When to make a doctor's appointment

See a healthcare professional if:

  • There is a personal or family history of gastrointestinal bleeding.
  • There are nosebleeds.
  • Lesions appear on the mouth or eye lining.
  • A lesion constantly bleeds.
