Causes of Skin Tags on the Neck

Causes of Skin Tags on the Neck

Skin tags, also known as acrochordons, are benign skin growths that arise due to the excessive development of the outer skin layer on the neck. These tags are composed of blood vessels and soft collagen fibers, encapsulated in a layer of skin. Collagen, a prevalent protein in the human body, plays a significant role in their formation. Importantly, skin tags are not cancerous and seldom give rise to skin cancer. They are quite common, with approximately 50% of individuals worldwide likely to experience them at some point in their lives. Below are some of the primary causes and risk factors contributing to the development of skin tags on the neck:

Friction

Friction in its various forms is one of the most common causes of skin tags, particularly in areas where the skin folds, such as the neck. This friction can occur between skin layers or from contact with clothing, jewelry, and other surfaces. Consequently, individuals with excess weight are at a higher risk of developing skin tags due to an increased number of skin folds and skin irritation.

Elevated Blood Sugar and Insulin Levels

The risk of developing skin tags increases with elevated blood sugar or insulin levels, particularly in individuals predisposed to Type 2 Diabetes Mellitus. However, the mechanism linking skin tag formation with blood sugar and insulin levels remains unidentified.

Human Papillomavirus

Low-risk human papillomavirus (HPV) infection may also be associated with the formation of skin tags on the neck. This type of infection can lead to warts, but it is essential to note that warts differ from skin tags in appearance and nature. Skin tags do not spread to others or to different parts of the body, and many individuals may be unaware that they carry an HPV infection.

Other Risk Factors

Several additional factors may increase the likelihood of developing skin tags on the neck, including:

• Pregnancy, due to hormonal fluctuations and elevated growth factor levels.
• A family history of skin tags.
• Disruptions in sex hormones, especially fluctuations in estrogen and progesterone levels.
• Increased growth factor levels, particularly in conditions such as acromegaly or gigantism, which result from elevated growth factor levels during childhood.

Association of Skin Tags with Other Health Disorders

Some researchers suggest that a sudden increase in the number of skin tags on the neck may indicate underlying health issues. In such cases, it is advisable to consult a physician for proper evaluation and treatment. Below are some health conditions that may contribute to the appearance of skin tags:

• Metabolic Syndrome: A cluster of risk factors that raises the likelihood of serious health conditions, such as heart disease, diabetes, and strokes. Diagnosis is typically made if at least three of the following risk factors are present:
  • Obesity, particularly with fat accumulation around the abdomen.
  • Elevated blood sugar levels.
  • High blood pressure.
  • Increased triglyceride levels.
  • Low levels of healthy cholesterol.
• Hyperlipidemia: Individuals with elevated blood fat levels commonly develop skin tags on the neck.
• Polycystic Ovary Syndrome (PCOS): In some cases, skin tags in women may indicate the presence of PCOS, which is associated with menstrual irregularities, the formation of small cysts on the ovaries, and elevated androgen levels.
• Birt-Hogg-Dubé Syndrome: A rare genetic disorder characterized by the development of multiple skin tumors and cancers in organs such as the colon and kidneys. Skin manifestations include skin tags, trichodiscomas, and multiple fibrofolliculomas.

When to Consult a Physician

It is essential to see a doctor if you notice new skin tags or are uncertain about their nature. This is important because they may resemble other skin conditions that could pose health risks, such as warts or moles, which can potentially be cancerous. A physician may conduct a visual examination and, if necessary, perform a biopsy to ascertain the nature of the tags.
