Questions about congenital nevi?
Dear Dr.
Wu,
I have several congenital nevi (birthmarks) on my back.
According to dermatological guidelines, the ABCDE criteria for assessing moles include: Asymmetry, Border irregularity, Color variation, Diameter (standard is within 0.6 cm), and Elevation.
I have observed that some of my congenital nevi do not meet these criteria, such as being somewhat asymmetrical, having irregular borders, varying colors, some exceeding 0.6 cm in size, and being slightly elevated.
However, these conditions have remained relatively unchanged for several decades.
I would like to ask Dr.
Wu the following questions:
Q1: Is it normal for congenital nevi to not meet the ABCDE criteria? My congenital nevi have not changed significantly over the past few decades, but their non-compliance with the ABCDE criteria has left me somewhat puzzled.
Q2: Following up on the previous question, although my congenital nevi have not changed significantly over the past few decades, they have shown slight increases in size, elevation, color variation, or hair growth as I age.
Is it normal for my congenital nevi to exhibit these "slow" subtle changes with age?
Q3: Generally speaking, what would you recommend for the management of normal congenital nevi? For example, should they be removed preventively or simply monitored?
Q4: Following up on the previous question, if I express a desire to remove "normal" congenital nevi at a dermatology clinic, would this be out-of-pocket expense or covered by health insurance?
Thank you, Dr.
Wu.

If you have concerns about your congenital mole, please seek medical attention directly, as it is not possible to discuss your condition without seeing the actual lesion.

More Info
Understanding congenital moles, or nevi, is essential for anyone who has them, especially if they exhibit characteristics that deviate from typical mole features. Your concerns about the appearance and changes in your congenital moles are valid, and I will address your questions based on current medical knowledge.
Q1: Is it normal for congenital moles to not meet the ABCDE criteria?
The ABCDE criteria (Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, and Evolving) are guidelines primarily used to assess acquired moles for potential malignancy, particularly melanoma. Congenital moles can often differ from these criteria. It is not uncommon for congenital moles to be asymmetrical, have irregular borders, or exceed the typical size threshold. These moles are usually benign and stable over time. However, any mole that exhibits significant changes in appearance, especially if it starts to itch, bleed, or change color rapidly, should be evaluated by a dermatologist.
Q2: Is it normal for congenital moles to undergo slow changes with age?
Yes, it is normal for congenital moles to undergo subtle changes as you age. Factors such as hormonal changes, sun exposure, and natural aging can cause moles to slightly enlarge, change color, or develop hair. The key point is that these changes should be gradual and not associated with any alarming symptoms. If you notice rapid changes or new symptoms, it would be prudent to consult a dermatologist for a thorough evaluation.
Q3: What is the recommended management for normal congenital moles?
For most congenital moles that are stable and show no signs of malignancy, the recommended approach is observation. Regular self-examinations and annual check-ups with a dermatologist can help monitor any changes. If a mole becomes bothersome or if there are cosmetic concerns, removal can be considered. However, preventive removal of benign congenital moles is typically not necessary unless there are specific concerns.
Q4: If I wish to remove a "normal" congenital mole, will it be covered by insurance?
In the United States, the removal of benign congenital moles is usually considered a cosmetic procedure and may not be covered by health insurance. However, if the mole shows signs of potential malignancy or causes discomfort, it may be covered. It is best to discuss your specific situation with your dermatologist, who can provide guidance on the necessity of removal and the potential for insurance coverage.
In summary, congenital moles can exhibit characteristics that differ from the ABCDE criteria without being a cause for concern, especially if they have remained stable over the years. Slow changes with age are generally normal, but any significant alterations should prompt a visit to a dermatologist. Regular monitoring and open communication with your healthcare provider are key to managing your skin health effectively. If you have further questions or concerns, do not hesitate to reach out to a specialist for personalized advice.
