It is most likely to be an acrochordon (fibroepithelial polyp, skin tag). This usually starts as a tiny skin tag and in areas where there is friction(such as skin folds-the intertriginous areas), they start to elongate over the course of months or even years.
Starting as sessile lesions, the gradually assume a pedunculated appearance.In some instances, their summit may even become large (mushroom-like). Due to friction, the overlying skin may ulcerate, leading to infection, or bleeding.
However, you must consult your doctor who will be able to examine the lesion and come to a definitive diagnosis. There is generally no need for any specific treatment unless,
- it is causing pain or discomfort,
- has ulcerated or has bled, or
- for cosmetic reasons.
Treatment is simple excision.
