An angioma is an overgrowth of blood vessels in the skin. There are two main types: cherry angiomas and spider angiomas. Both types of angiomas are benign (non-cancerous).
Cherry angiomas are deep red to purple round growths, which start to develop in adults around the age of thirty. Spider angiomas, found in both children and adults, are a collection of small, superficial blood vessels radiating out of a central red bump, resembling spider legs.
If injured, they can bleed and become infected.
Spider angiomas are caused by overexposure to the sun, skin injuries, pregnancies, or liver diseases. The cause of cherry angiomas are unknown and largely thought to be caused by genetics.
Electrosurgery uses electric currents to coagulate and destroy the blood vessels
Lasers can target hemoglobin to heat and destroy the blood vessels
A qualified health professional may remove the angioma or spider angioma by surgically removing it.
