Signs and Symptoms
The most common locations for spider angiomas include:
  • Face, especially below the eyes and over the cheekbones
  • Neck
  • Upper trunk
  • Backs of the hands and fingers
  • Forearms
  • Ears
Spider angiomas may appear singly or as multiple lesions. Each spider angioma appears as a small (1–10 mm), bright red spot. Upon closer inspection, you will see a central red dot with tiny red lines radiating out from the center.

Rarely, they may bleed if injured (traumatized).
