What should you know about port wine stain bleeding?

A port-wine stain, also called a capillary malformation, contains widened small blood vessels near the skin surface. The colour can range from pink to red, purple, or deeper shades. The stain itself is not usually an open wound. Blood may appear when the area is cut, scraped, irritated, or affected by dryness. Over time, some stains become thicker or develop a pebbled surface, which can make minor trauma more likely. Bleeding alone does not establish a serious diagnosis, but the change should be looked at if there was no clear injury.

Wash your hands, place clean gauze or a soft cloth over the spot, and apply steady gentle pressure without repeatedly lifting it to check. Once bleeding has stopped, rinse away visible dirt with clean water and cover the area if clothing will rub it. Avoid picking a crust, shaving directly over it, or applying harsh antiseptics. Keep the skin moisturised if dryness contributes to scratching. A dermatologist can examine the surface and discuss options such as Pulsed Dye Laser Treatment when treatment is appropriate.

Arrange prompt clinical advice if bleeding starts without an obvious injury, returns, lasts despite sustained pressure, or comes from a new raised or ulcerated area. Seek urgent care for heavy bleeding, faintness, marked swelling, severe pain, spreading redness, pus, or fever. For a child with a facial stain, mention any eye or neurological symptoms to the clinician promptly.

Ask what may have triggered the bleeding, whether the surface needs treatment, how to protect it during washing or sport, and whether Pulsed Dye Laser Treatment is suitable for the stain’s depth and location.
