Telangiectasis

Telangiectasis is a medical condition in which dilated, thin-walled blood vessels, called telangiectasias, form on the skin, mucous membranes, or internal organs. These blood vessels can form anywhere on the body but are most commonly found on the face and legs. Telangiectasias usually appear as small, red spots that look like spider webs. They can range in size from a few millimeters to several centimeters across. These spots are caused when the walls of the blood vessels become weak and dilated, allowing the blood to leak out. Telangiectasias can be caused by a number of different conditions, including sun exposure, aging, genetics, and certain medical conditions such as rosacea, Ehlers-Danlos syndrome, and systemic lupus erythematosus. In some cases, telangiectasias can be caused by medication or medical treatments such as radiation therapy. Telangiectasias can cause a variety of symptoms, depending on the location and size of the vessels. Common symptoms include itching, burning, and pain around the affected area. In some cases, telangiectasias can lead to bleeding and infection. Treatment for telangiectasias varies depending on the underlying cause. In some cases, they may resolve on their own without treatment. However, if the telangiectasias are causing symptoms or if they are cosmetically unappealing, treatment may be necessary. Treatment options include laser therapy, topical medications, and surgical removal.
