This image displays a spider angioma. A spider angioma is a dilated, small capillary. Spider angiomas are bright red, flat, and easily blanch when you press your finger on them. This image displays a typical spider angioma.  This image displays two spider angiomas on the upper lip. This flat spider angioma demonstrates why it is often called a "spider," with tiny blood vessels radiating out from a central larger blood vessel. Spider angiomas are usually deep red but will fade easily when you press on the lesion with your finger.

Treatments Your Provider May Prescribe
The diagnosis of a spider angioma is usually easy to make, but some lesions may not be obvious and may require a skin biopsy to confirm the diagnosis. The biopsy procedure involves:
  1. Numbing the skin with an injectable anesthetic.
  2. Sampling a small piece of skin by using a flexible razor blade, a scalpel, or a tiny cookie cutter (called a "punch biopsy"). If a punch biopsy is taken, a stitch (suture) or two may be placed and will need to be removed 6–14 days later.
  3. Having the skin sample examined under the microscope by a specially trained physician (dermatopathologist).
If the diagnosis of spider angioma has been confirmed, no treatment is necessary. However, if your child is self-conscious about the area or if it frequently bleeds, the doctor may offer one of the following procedures:
  • Burning with an electric needle (electrocautery or electrodesiccation)
  • Using a laser to destroy the central blood vessel
