Western Summary

Angiomas are benign overgrowths of blood vessels in the skin. There are three main types: cherry angiomas, spider angiomas, and venous lakes. All three types of angiomas are harmless. However, if injured, they can bleed and get infected. 


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. It is a benign overgrowth of blood vessels in the skin.



Spider angiomas are caused by overexposure to the sun, skin injuries, pregnancies, or liver diseases. The cause of cherry angiomas and venous lakes are unknown. 


  • 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
