Telangiectasis, also known as telangiectasia, is a medical term that refers to the abnormal dilation or widening of small blood vessels or capillaries, resulting in visible red or purple spider-like patterns on the skin or mucous membranes.
Telangiectasis can occur in various parts of the body, including the face, legs, arms, and even internal organs such as the lungs, digestive tract, or nasal passages. These small dilated blood vessels may appear as fine lines, web-like networks, or clusters of bluish or reddish dots. Their appearance may be more pronounced when the affected area is pressed or irritated.
There are several factors that can contribute to the development of telangiectasis. These may include genetic predisposition, chronic sun exposure, aging, hormonal changes (such as during pregnancy), certain medications, injury, or underlying medical conditions like rosacea, liver disease, or autoimmune disorders.
While telangiectasis is usually harmless and doesn't cause significant symptoms, it can be a cosmetic concern for some individuals. In certain cases, telangiectasis may be associated with bleeding or be an indication of an underlying medical condition requiring further evaluation or treatment.
Treatment options for telangiectasis depend on the cause, size, and location of the affected blood vessels. Common treatments may include laser therapy, electrocautery, sclerotherapy, or topical medications. These interventions aim to reduce or eliminate the visible blood vessels or improve any associated symptoms.
