An angioma is an overgrowth of blood vessels in the skin.
There are two main types: cherry angiomas and spider angiomas. 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.
Both types of angiomas are benign (non-cancerous). However, 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.
Several procedures can be used to treat cherry angiomas and spider angiomas:
- Electrosurgery: using electric currents to coagulate and destroy the blood vessels
- Cryotherapy: using liquid nitrogen to freeze the blood vessels
- Lasers can target hemoglobin to heat and destroy the blood vessels
- Surgical excision: a qualified health professional may remove the angioma or spider angioma by surgically removing it.
