Acrochordon

Acrochordon (plural: acrochorda), commonly known as a skin tag, is a small, benign tumor that forms primarily in areas where the skin forms creases, such as the neck, armpit, and groin. They may also occur on the face, usually on the eyelids. Skin tags are generally harmless and painless, and do not grow or change over time. They are composed of a core of fibers and ducts, nerve cells, fat cells, and a covering or epidermis.

Characteristics

Acrochorda are typically flesh-colored or slightly darker and can vary in size from a few millimeters to a few centimeters. They are often attached to the skin by a small, thin stalk called a peduncle. While they are usually asymptomatic, they can become irritated if they are rubbed by clothing or jewelry.

Causes

The exact cause of acrochorda is not well understood, but they are believed to be associated with genetics, obesity, and diabetes. Hormonal changes, particularly during pregnancy, may also contribute to their development. Additionally, they are more common in older adults.

Diagnosis

Diagnosis of acrochorda is typically made through a physical examination. In most cases, no further testing is required. However, if there is any doubt about the diagnosis, a biopsy may be performed to rule out other skin conditions.

Treatment

Treatment is not usually necessary unless the skin tags are causing discomfort or cosmetic concerns. Common methods of removal include:

• Cryotherapy (freezing the skin tag with liquid nitrogen)
• Cauterization (burning off the skin tag)
• Ligation (tying off the skin tag with surgical thread to cut off its blood supply)
• Excision (cutting off the skin tag with a scalpel or scissors)

Prevention

There is no known way to prevent acrochorda from forming. Maintaining a healthy weight and managing conditions like diabetes may reduce the likelihood of developing skin tags.
