A<unk> , or acrochordon (pl. acrochorda), is a small benign tumor that forms primarily in areas where the<unk>  forms creases (or rubs together), such as the neck, armpit and groin. They may also occur on the face, usually on the eyelids. Though<unk> s up to half an inch (12.7 mm) long have been seen, they are typically the size of a grain of rice. The surface of an acrochordon may be smooth or irregular in appearance and is often raised from the surface of the<unk>  on a fleshy stalk called a peduncle. Microscopically, an acrochordon consists of a fibrovascular core, sometimes also with fat cells, covered by an unremarkable epidermis. However,<unk> s may become irritated by shaving, clothing, jewellery or eczema.
