Spider angiomas

This photograph shows two spider angiomas (spider telangiectasias) on the arm of a pregnant person. A central feeding vessel, most easily seen in the lesion on the right, leads to other telangiectatic vessels, arranged in the shape of a spider, best appreciated in the lesion on the left. Pressure over the central vessel with the end of a paper clip or a glass slide causes the entire lesion to blanch. Similar lesions can be seen in patients with cirrhosis and are most commonly seen on the upper chest, face, and back.
