Raised Moles in the Armpit: Risks and Removal Options - Dermatology

More Info

---

When it comes to raised moles or skin lesions in the armpit area, there are several important considerations regarding their nature, potential risks, and removal options. Let's address your questions one by one.

1. Risk of Malignant Transformation: Raised moles, also known as dermatofibromas or skin tags, are generally benign. However, any skin lesion can potentially undergo changes that may lead to malignancy, especially if they exhibit characteristics such as asymmetry, irregular borders, multiple colors, or an increase in size. In clinical practice, while it is uncommon for benign moles to transform into malignant lesions, there are documented cases where benign-appearing moles have shown atypical features upon examination. Therefore, it is essential to monitor any changes in your mole over time, especially since it is located in an area prone to friction, which can sometimes lead to irritation or changes in the mole's appearance.

2. Management of the Raised Mole: Given that your mole has been stable for several years and has not changed significantly, regular observation may be sufficient. However, because it is located in a friction-prone area, it may be wise to consider removal, especially if it causes discomfort or irritation. If you notice any changes in size, color, or shape, or if it begins to bleed or itch, it would be prudent to consult a dermatologist for further evaluation. They may recommend a biopsy to rule out any malignancy if there are concerning features.

3. Removal Options: If you decide to proceed with removal, there are several methods commonly used in medical facilities. For a mole of approximately 2mm in size, the following options are typically considered:
- Excisional Surgery: This is a common method where the mole is surgically removed along with a small margin of surrounding skin. This method is often preferred if there is any concern about the mole's characteristics, as it allows for thorough examination of the tissue.

- Shave Excision: In this technique, the mole is shaved off at the level of the surrounding skin. This method is less invasive and may be suitable for smaller moles that are not suspected to be malignant.

- Cryotherapy: This involves freezing the mole with liquid nitrogen. It is generally used for superficial lesions and may not be the best option for deeper or larger moles.

- Laser Removal: Laser treatments can be effective for certain types of moles, particularly those that are pigmented. However, this method may not provide a complete removal, and there is a risk of scarring.

In conclusion, while your raised mole appears stable, it is essential to monitor it for any changes due to its location. If you experience discomfort or notice any changes, consulting a dermatologist is advisable. They can provide a thorough examination and recommend the most appropriate removal method based on the mole's characteristics and your personal preferences. Regular skin checks and awareness of any new or changing lesions are key components of maintaining skin health.
