Are any complications associated with acrochordons?

Yes. The most common complications are recurrent trauma to individual lesions (e.g., laceration with a shaving razor) or spontaneous torsion and infarction of a pedunculated lesion. When a pedunculated lesion twists on its stalk, the blood supply is compromised and tissue ischemia occurs. Usually, sudden pain, swelling, necrosis, and even secondary infection result. Often, this sequence of events results in disappearance of the lesion.
