Vascular lesions result from dilations of blood vessels, either congenital or acquired over time. Examples include nasal telangiectasias, which are small, dilated blood vessels on the surface of the skin that appear red or purple due to factors such as prolonged UV exposure, excessive alcohol consumption, pregnancy, long-term steroid use, or hormonal treatments.
