A skin tag, or acrochordon (pl. acrochorda), is a small benign tumor that forms primarily in areas where the skin forms creases (or rubs together), such as the neck, armpit and groin. They may also occur on the face, usually on the eyelids. Perianal skin tags can be associated with Crohn's disease. Acrochorda are generally harmless and painless and usually do not grow or change over time. Though tags up to a half-inch 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 skin 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, tags may become irritated by shaving, clothing, jewellery or eczema.
Moles are typically small, dark skin growths that develop from pigment-producing cells in the skin but they can be raised off the skin and very noticeable or they may contain dark hairs. The special cells that contain the pigment melanin are responsible for the brown color. They can be round, oval, flat, or raised. Most moles are brown, but colors can range from pinkish flesh tones to yellow, dark blue, or black.
Determine whether a biopsy is needed. At your appointment, the doctor will examine your mole's shape, borders, size, color, and surface texture, to see whether it appears to be cancerous. If the mole exhibits common symptoms of melanoma or another type of skin cancer, the doctor will order a biopsy to test whether cancer cells are present. If it doesn't, the doctor will be able to go ahead and remove the mole. The sample will often be sent for analysis even if the mole does not appear to be cancerous.
There are a few at-home skin tag removal kit options you can pick up from pharmacies - some products are designed to freeze small skin tags, others involve wrapping small rubber bands around the skin tag to cut off the blood supply, and we’ve also seen ones where you apply a solution to the tag and cover it in a bandaid to hinder the supply of oxygen.
