Acrochordons, also known as skin tags or fibroepithelial polyps, are common benign cutaneous growths. They present as small, skin-colored or brown, soft papules and are most commonly found in areas of frequent friction such as the eyelids, neck, axillae, and inguinal area. Acrochordons are usually asymptomatic but can become irritated by clothing or jewelry. Occasionally, skin tags twist upon their own stalk, which leads to strangulation of their blood supply and spontaneous necrosis of the skin tag. Acrochordons are associated with increasing age, pregnancy, diabetes, and obesity. Men and women are affected equally, and there is no difference in prevalence among different ethnicities and races.

Acrochordons can also be a feature of the autosomal-dominantly inherited Birt-Hogg-Dubé syndrome. They can also be seen in large numbers in tuberous sclerosis. They are increased in number in acromegaly and are sometimes associated with acanthosis nigricans.
