acrochordons

Acrochordons, commonly known as skin tags, are small, benign skin growths that project from the surface of the skin on a thin stalk. They are composed of loosely arranged fibrous tissue and blood vessels covered by normal epidermis.

These lesions are typically soft, flesh-colored or slightly brown, and may range from a few millimeters to a centimeter or more in size. They commonly occur in areas where the skin folds and experiences friction, such as the neck, armpits, groin, and eyelids. They may become irritated by clothing, jewelry, or shaving.

Risk factors include obesity, type 2 diabetes or insulin resistance, aging, and pregnancy. A family tendency has also been observed. The exact cause is not fully understood, but friction and hormonal factors are thought to contribute. Skin tags are non-contagious and do not indicate cancer.

Diagnosis is usually clinical, based on appearance. In atypical cases or when changes occur, a clinician may biopsy the lesion to confirm that it is benign and to rule out other conditions.

Treatment is not required unless the lesion is bothersome or for cosmetic reasons. Removal methods include simple snip excision with sterile scissors, cryotherapy with liquid nitrogen, curettage with cauterization, laser therapy, or surgical removal of the stalk. Recurrence can occur, particularly if friction persists or underlying conditions such as obesity or diabetes remain.

Overall, acrochordons are common, harmless skin lesions with a favorable prognosis. Monitoring for unusual growth, rapid change, or persistent irritation is advised, and medical removal can be considered if desired.
