Telangiectasia

Telangiectasias are permanent dilations of very small blood vessels that show through the skin as fine reddish or purple lines, in the shape of branches or spider webs. They frequently appear on the face, legs, or around the nose, and are usually more of a cosmetic finding, although at times they accompany other conditions.

Common causes: They are associated with factors such as heredity, prolonged sun exposure, hormonal changes, aging of the skin, or venous pressure in the legs.

When should they be checked? If the marks increase rapidly, bleed, or are accompanied by other symptoms, an evaluation is reasonable to rule out underlying causes.

Which specialist handles them? A dermatologist can examine them in detail, and the general practitioner guides an initial review. It is advisable to discuss your questions with a professional who can evaluate your particular case before deciding on any course of action.
