Telangiectasis
Telangiectasis (pronunciation: tɛˌlæn.dʒiː.ɛkˈteɪ.sɪs) is a medical condition characterized by the dilation of small blood vessels, capillaries, arterioles, or venules. The term is derived from the Greek words "telos" meaning end, "angeion" meaning vessel, and "ektasis" meaning dilation.
Definition
Telangiectasis refers to small dilated blood vessels that can occur near the surface of the skin or mucous membranes. These appear as tiny, red, spider-like lines and can develop anywhere on the body but are commonly seen on the face and legs.
Causes
Telangiectasis can be caused by several conditions including Rosacea, Ataxia Telangiectasia, Hereditary Hemorrhagic Telangiectasia, Crest Syndrome, and prolonged use of topical corticosteroids. It can also be a result of aging, pregnancy, or exposure to the sun or extreme cold.
Symptoms
The primary symptom of Telangiectasis is the appearance of small, red, spider-like lines on the skin. These lines are actually dilated blood vessels. They can be seen more clearly when the skin is stretched. Other symptoms may include bleeding, discomfort, and in some cases, more serious complications depending on the underlying cause.
Treatment
Treatment for Telangiectasis depends on the underlying cause. Options may include laser therapy, sclerotherapy, or surgery. In some cases, no treatment is necessary if the Telangiectasis is not causing any discomfort or complications.
