Angiomas are growths that are typically benign (noncancerous). They're made of small blood or lymphatic vessels and appear red or purple on the skin. They can develop in anyone, but they're most common among those with fair skin.
Often called "strawberry marks," hemangiomas are benign growths commonly seen in infants and children. Made up of small blood vessels, they appear as red or purple discoloration. They often resolve by age 10.
No, angiomas and hemangiomas are not typically dangerous. However, if you notice changes in shape, color, or size, be sure to consult a dermatologist for a skin check.
While angiomas and hemangiomas don't typically require treatment, you may wish to remove them for cosmetic reasons. In that case, they can be effectively treated with laser treatment or liquid nitrogen to remove the blood vessels and damaged cells. Treatment may cause minor discomfort but is generally well-tolerated.
