Cutaneous Vascular Anomalies – Spider Angioma

June 1st, 2013

Spider Angiomas are a very common skin lesion that I frequently encounter in both my The Woodlands dermatology and Conroe dermatology offices.  Clinically, a Spider Angioma has a central red pin head size “body” with very small “legs” that project in all directions.  When a Spider Angioma is pressed with a glass slide it can be noted that the lesion dissappears as the blood is forced out of it, which subsequently returns when the pressure is release.  They are most commonly seen in young women and children on the face, neck and upper chest.  Pregnancy is also known to cause Spider Angiomas as well as diseases of the liver. In many patients the Spider Angiomas involute without treatment, but laser and electrocautery has been effective at eliminating persistent lesions.
