What condition results from the age-related loss of elasticity in capillary walls, leading to dilation and sometimes bursting?

• A. Varicose veins
• B. Telangiectasia
• C. Spider veins
• D. Rosacea

Answer: (B)

The correct answer is telangiectasia, which refers to the small dilated blood vessels that become visible on the skin's surface, often as a result of factors such as aging. As individuals age, the elasticity of the capillary walls diminishes. This loss of elasticity can cause the capillaries to dilate and potentially burst, leading to the appearance of these small, red or purple vessels on the skin.

Telangiectasia commonly appears on the face and legs and is characterized by its fine, prominent lines. Although other conditions like varicose veins can also be related to vascular issues, they are typically larger and occur deeper in the venous system rather than at the level of capillaries. Spider veins, while similar in appearance, are essentially a type of telangiectasia but generally refer to specific patterns that resemble a spider or tree branches. Rosacea is a skin condition that may include telangiectasia as a symptom but involves additional signs like redness, flushing, and sometimes acne-like breakouts.

Thus, telangiectasia specifically encompasses the age-related loss of elasticity in capillary walls, leading to their dilation and the observable skin changes described in the question.
