Telangiectasia

In dermatology and cosmetology, vascular skin lesions occupy a significant place. Among them, telangiectasia (TAE) is common (from the Greek telos - ending, angеion - vessel and ektasis - expansion). The term was first proposed by Von Graf in 1807 to describe the superficial vessels of the skin visible to the human eye, which range in diameter from 0.1 to several millimeters. The more common name is “spider veins”.
Telangiectasias are dilated superficial capillaries. Possible causes include hormonal imbalances, trauma, the use of certain medications, autoimmune diseases, genetic abnormalities, and they can also occur idiopathically (i.e., without a clear cause). A very important and at the same time accessible diagnostic technique is diascopy (pressure with a glass slide), in which the pathological focus is not detected.
