What is telangiectasia?

  1. Inflammation of the hair follicle

  2. Distended capillaries

  3. A type of skin cancer

  4. Excessive sweating

The correct answer is: Distended capillaries

Telangiectasia refers to the appearance of distended or enlarged capillaries, generally located close to the surface of the skin. This condition is characterized by small, dilated blood vessels that can become visible as red or purple lines or spots on various parts of the body, particularly on the face. Telangiectasia can be caused by a variety of factors, including sun exposure, skin trauma, certain medical conditions, and age. The other options represent different skin or bodily functions. Inflammation of the hair follicle pertains to folliculitis, which is an entirely different condition characterized by redness and swelling around hair follicles. Skin cancer encompasses abnormal growths, which are not typically associated with mere capillary dilation. Lastly, excessive sweating refers to hyperhidrosis, unrelated to the vascular changes seen in telangiectasia. Understanding the specific characteristics of telangiectasia helps in recognizing and managing skin conditions effectively.
