Skin tags are common, acquired benign skin growths that resemble a small, soft balloon suspended on a slender stalk. Skin tags are harmless growths that can vary in number from one to hundreds. Males and females are equally prone to developing skin tags. Obesity seems to be associated with skin tag development. Although some skin tags may fall off spontaneously, most persist once formed. The medical name for skin tag is acrochordon. Some people call them "skin tabs."
