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.

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.
