Treating Suspicious Nevi

Suspicious nevi, also known as atypical moles, are moles that exhibit irregular features in size, shape, color, or texture. While not all atypical moles are cancerous, they may carry a higher risk of developing into melanoma. Regular monitoring and early intervention can help prevent complications.

Atypical nevi in the spectrum between benign moles and melanoma are also known as dysplastic nevi. They can be classified into three categories based on their degree of abnormality: mild, moderate, and severe. Mild and moderate atypical nevi may only require observation, while severe atypical nevi often share similarities with melanoma in situ (MMIS). Due to this increased risk, excision with margins similar to MMIS is typically recommended to ensure complete removal and reduce the likelihood of progression to melanoma.

Identifying Suspicious Nevi

The ABCDE rule is a helpful guideline for identifying concerning moles:

• A – Asymmetry: One half of the mole doesn’t match the other.
• B – Border: Edges are irregular, blurred, or uneven.
• C – Color: Varies throughout, with shades of brown, black, red, or blue.
• D – Diameter: Larger than 6mm (about the size of a pencil eraser).
• E – Evolving: Any change in size, shape, color, or texture over time.

Other warning signs include itching, bleeding, tenderness, or the sudden appearance of a new mole.

What Causes Suspicious Nevi?

While most moles are harmless, certain factors can increase the likelihood of developing atypical or suspicious nevi. These include:

• Genetics & Family History: Individuals with a family history of atypical moles or melanoma are at a higher risk.
• Excessive UV Exposure: Frequent sun exposure or use of tanning beds can lead to abnormal skin changes.
• History of Severe Sunburns: Having multiple blistering sunburns, particularly in childhood, increases the likelihood of developing atypical moles.
• Having a High Number of Moles: Those with more than 50 moles on their body are at a greater risk for developing atypical nevi.
• Weakened Immune System: Conditions or medications that suppress the immune system may contribute to mole abnormalities.

Treatment Options for Suspicious Nevi

Our experienced surgeons specialize in evaluating and treating suspicious moles with the most advanced techniques available. When a mole shows concerning features or is confirmed through biopsy to be precancerous, we work closely with you to develop the most appropriate treatment plan.

Excisional Surgery

Excisional mole removal is our primary method for treating suspicious or high-risk moles. During this procedure, our surgeons remove the entire mole and a small margin of surrounding healthy skin under local anesthesia to ensure your comfort. This approach not only eliminates the abnormal cells but also minimizes the risk of recurrence.

Excisional surgery is particularly recommended for severe atypical nevi, as they share characteristics with melanoma in situ (MMIS). By removing the mole with appropriate margins, we provide the best possible protection against the potential progression to melanoma.
