Unusual Changes After Mole Removal: What You Need to Know - Dermatology

After mole removal, it is not uncommon to experience some changes in the area where the mole was excised. However, the symptoms you are describing—specifically, the mole regrowing to about half its original size and the presence of an unusual odor—are concerning and warrant further investigation.

Firstly, it is important to understand that when a mole is removed, the healing process can vary significantly from person to person. Typically, the area may appear red, swollen, or even slightly raised as it heals. Scabbing and peeling can also occur, which are normal parts of the healing process. However, if a mole begins to regrow or if there is an unusual odor, this could indicate a few potential issues.

1. Incomplete Removal: If the mole was not completely excised, it may regrow. This is particularly true for moles that have deeper roots or if the removal was not thorough. In some cases, remnants of the mole can remain beneath the skin, leading to regrowth.

2. Infection: The presence of an odor can be a sign of infection. Post-surgical infections can occur if bacteria enter the wound, leading to symptoms such as increased redness, swelling, warmth, and discharge that may have a foul smell. Infections require prompt medical attention and may need antibiotics for treatment.

3. Skin Changes: Sometimes, the skin can react to the removal process, leading to changes in texture, color, or even the formation of new growths. These changes can sometimes be benign but should be monitored closely.

4. Dysplastic Nevi: If the mole was atypical or dysplastic (having irregular features), there is a possibility that it could return or that new atypical cells could form in the area. This is why it is crucial to have any unusual changes evaluated by a healthcare professional.

Given these possibilities, it is essential to follow up with your dermatologist or the healthcare provider who performed the mole removal. They can conduct a thorough examination, possibly including a biopsy of the regrown mole, to determine the nature of the changes and whether any treatment is necessary.

In the meantime, here are some general care tips for the area post-mole removal:
- Keep the Area Clean: Gently clean the area with mild soap and water. Avoid using harsh chemicals or scrubbing the area.

- Avoid Picking or Scratching: This can introduce bacteria and lead to infection.

- Monitor for Changes: Keep an eye on the area for any changes in size, color, or odor, and report these to your doctor.

- Follow Post-Operative Instructions: If your doctor provided specific care instructions after the mole removal, be sure to follow them closely.

In conclusion, while some changes can be expected after mole removal, the symptoms you are experiencing—particularly the regrowth and odor—are not typical and should be evaluated by a medical professional as soon as possible. Early intervention can help address any potential complications and ensure proper healing.
