SymptomsThe tag is usually small, which sticks out of the skin with a short narrow stalk connecting it to the skin and may be a half-inch long. It is the same color as skin, or a little darker.
It is usually painless and does not grow or change. However, it may be irritated from rubbing by clothing or other materials.
CausesIt is not known what causes skin tags. However, the following factors may play a role:
- Chaffing and irritation from skin rubbing together
- High levels of growth factors, particularly during pregnancy or in acromegaly (gigantism)
- Insulin resistance
- Human papilloma virus (wart virus)
