Angiomas are benign growths comprised of small blood vessels. They can appear anywhere on the skin and typically do not require treatment unless they bleed or are considered cosmetically bothersome. The cause of most angiomas is unknown, with the exception of cherry angiomas which form due to aging. Angiomas can appear on individuals of any age.

- Cherry Angiomas: Bright red patches of grouped together blood vessels, typically small in size and especially common after age 30. Cherry angiomas are often inherited and are usually harmless, although they may bleed profusely if injured.
- Spider Angiomas: Vascular lesions with a central grouping and radiating outward lines resembling spider legs. When many spider angiomas are present, it can be a sign of liver damage.
- Venous Angioma (DVA): Abnormal draining of tissue in the brain affecting a small cluster of veins. DVAs are usually present at birth but may not develop until later in life. The cause and risk factors of venous angiomas is unknown. Typically, DVAs present no symptoms and do not require treatment.
Treatment for most angiomas is not necessary. However, if you have a cherry angioma or spider angioma that bleeds or is cosmetically undesirable, your treatment options include:
- Cautery: the angioma is burned off
- Cryotherapy: the angioma is frozen off
- Laser: concentrated light destroys the angioma
- Excision: the angioma is surgically removed
Angiomas can sometimes recur after treatment.
