What are distended capillaries caused by constant overdilation known as?

1. Varicose veins

2. Telangiectasis

3. Spider veins

4. Hemangiomas

The correct answer is: Telangiectasis

Telangiectasis refers to small, dilated blood vessels visible near the surface of the skin, which are often a result of constant overdilation. When capillaries become distended and remain enlarged, they create a network of small, red or purple lines on the skin, commonly known as spider veins. These are typically associated with various factors including genetics, lifestyle, and hormonal changes, and they can appear on the face and legs. The term specifically describes the condition of the blood vessels themselves, making it the best fit for the definition provided in the question. While varicose veins also involve the dilation of veins, they are larger and often painful, distinguished from the finer appearance and typically more cosmetic concern posed by telangiectasis. Spider veins is another term that describes a similar appearance to telangiectasis but is more commonly used in layman's terms for superficial manifestations. Hemangiomas, on the other hand, are benign tumors made up of blood vessels and can present as raised or flat lesions but do not fit the description of distended capillaries due to continuous overdilation.
