Generalized essential telangiectasia is characterized by the following characteristics:
- Red or pink dilated capillary blood vessels, usually less than 0.2 mm in diameter in a lace or branch-like pattern
- It is most often found on the feet, ankles, and legs, but can appear on the trunk and upper parts of the body, such as the hands and arms.
- When pressure is put on the affected sites, pallor occurs temporarily before blood fills the space again
