Skin tags, also known as acrochordons, are very common soft, fleshy, skin-colored round to oval pedunculated papules with predilection for the neck, axillae, trunk, groin, and eyelids of middle-aged and elderly people. Skin tags are benign, and predisposing factors include obesity, pregnancy, menopause, and acromegaly. In the past, there was thought to be an association with colonic polyps, but more recently this relationship has been disputed.

Patients are usually bothered by the cosmetic appearance of skin tags. They are usually asymptomatic, but can be irritating when repeatedly caught on clothing and painful when a lesion twists on its own stalk and infarcts. The lesions are single or multiple, 1 to 10 mm in diameter, soft, flesh-colored or hyperpigmented, oval or round pedunculated fleshy papules, and tend to increase in size over time.
