What should you know about blood skin tag?

Tags commonly occur where skin or clothing rubs, such as the neck, armpits, groin and beneath the breasts. Because other growths may resemble a skin tag, a new, dark, painful or repeatedly bleeding lesion should not be assumed to be harmless.

A typical skin tag is a soft piece of skin attached by a narrow stalk. Its surface may tear if it catches on a necklace, bra edge or razor. A twisted stalk can become tender and dark as its blood supply is disrupted.

Bleeding without a clear injury, continued growth, an open sore, firm texture or irregular pigment changes the clinical picture. A dermatologist can inspect the attachment and surface, compare it with nearby lesions and decide whether removal and laboratory examination are appropriate.

Hold clean gauze firmly over the tag until bleeding stops. Wash gently with water, pat the area dry and use a small non-stick dressing to prevent further rubbing. Choose loose clothing until the surface has healed.

Do not pull, cut or tie off the tag, and do not use wart acid or burning products. These methods can damage surrounding skin, introduce infection and make it harder to identify what the lesion was. Professional options can include cryotherapy, electrosurgery or careful snipping after the diagnosis is confirmed.

Seek urgent care if steady pressure fails to stop bleeding, the wound is deep, or you feel faint. Increasing redness, heat, swelling, pus or fever warrants prompt review for infection.

Arrange a skin examination if the lesion bleeds again, becomes very painful, changes quickly, develops uneven colour or does not heal. People taking medicines that affect clotting should mention them when seeking advice and should not stop them without instructions from the prescriber.

Ask how confident the clinician is that the growth is a skin tag, which removal method fits its location and size, how to care for the wound, and whether the tissue should be examined in a laboratory.
