A black skin tag can be a sign of a problem, but not always.
What Causes a Skin Tag to Turn Black?
Skin tags are generally harmless growths, but a black or dark brown skin tag often indicates that the blood supply to the tag has been cut off. This can happen if:
- Torsion (Twisting): Skin tags attached by a narrow stalk are susceptible to twisting. This twisting action restricts blood flow.
- Trauma: Injury or irritation to the skin tag can also interrupt blood supply.
- Necrosis: Without blood flow, the skin tag tissue dies, causing it to darken.
When is a Black Skin Tag a Concern?
While often benign, a black skin tag warrants attention because it could also indicate something more serious. Specifically, you should consult a doctor if:
- The black skin tag is painful or inflamed.
- The color change is sudden and accompanied by other symptoms.
- You are unsure about the cause of the change.
- The tag is bleeding or oozing.
- There are other concerning skin changes around the tag.
A doctor can rule out other conditions that can resemble a dark skin tag, such as:
- Moles: Atypical moles can sometimes resemble skin tags.
- Seborrheic Keratoses: These are benign skin growths that can be dark in color.
- Skin Cancer: Although rare, skin cancer can sometimes mimic the appearance of a skin tag.
What to Do if You Have a Black Skin Tag
- Monitor the skin tag: Keep an eye on it for any changes in size, shape, color, or symptoms.
- Avoid irritating the tag: Don't pick, scratch, or rub the tag.
- Consult a doctor: If you're concerned, it's always best to seek professional medical advice. They can properly diagnose the condition and recommend appropriate treatment if necessary. Treatment usually involves simple removal.
