Moles that have been removed can sometimes grow back?

Hello Dr.
Lee, about five years ago I developed psoriasis in my groin area.
It can be controlled with medication, but it cannot be completely cured, and it tends to flare up again every summer.
On one occasion, due to itching, I accidentally scratched a pre-existing mole, and later noticed that a growth about one centimeter wide and less than 0.5 centimeters high began to develop in that area.
It has been present for about three to four years now, without any increase in size or change in shape.
It appears (or feels) scaly, similar to durian, and it does not ooze, itch, or break the skin.
Recently, I impulsively picked at it; it can be removed easily and has no odor, but it returns to its original state after a few days.
Referring to the chart at https://zhuanlan.zhihu.com/p/32175682, the growth on my body resembles the second item in the "mole" column on the left side of the chart.
I can pinch it and lift it, and my intuition suggests it is just on the epidermis.
I would like to ask Dr.
Lee, based on my description, if there are no further changes, can I ignore it? If I wish to seek medical advice, should I consult a dermatologist or a urologist? Thank you for your guidance.

More Info

When it comes to moles or skin lesions that seem to grow back after being picked at, there are several factors to consider. Based on your description, it sounds like you may be dealing with a benign skin lesion, possibly a type of keratosis or a mole that has been irritated. Here’s a breakdown of why this might be happening and what you should consider moving forward.

Why Does My Mole Keep Growing Back?
1. Skin Regeneration: The skin has a remarkable ability to heal and regenerate. When you pick at a mole or any skin lesion, you may inadvertently cause irritation or trauma to the area. The body responds to this trauma by sending cells to repair the damage, which can lead to the lesion reappearing. If the underlying cells are still present, they can proliferate, causing the mole to grow back.

2. Type of Lesion: The characteristics you describe—scaly, resembling a durian, and not causing pain or discharge—suggest that it may not be a typical mole (nevi) but rather a different type of skin growth, such as a seborrheic keratosis or a benign tumor. These types of lesions can be persistent and may recur if not completely removed.

3. Underlying Conditions: You mentioned having psoriasis, which is a chronic skin condition that can lead to the formation of plaques and can affect how your skin heals. Psoriasis can sometimes complicate the healing process and may lead to the development of new lesions in response to irritation.

4. Irritation and Picking: Picking at the mole can lead to further irritation and inflammation, which may cause it to grow back. The act of picking can also introduce bacteria, leading to potential infections, although you mentioned that there is no pus or odor, which is a good sign.

What Should You Do?
1. Avoid Picking: The first step is to avoid picking at the mole or lesion. This will allow your skin to heal properly and may prevent the lesion from returning.

2. Monitor Changes: Keep an eye on the mole for any changes in size, shape, color, or texture. If it begins to change or if you notice any new symptoms (like itching, bleeding, or pain), it’s important to seek medical advice.

3. Consult a Dermatologist: Given your history and the characteristics of the lesion, it would be wise to consult a dermatologist. They can provide a thorough examination and may recommend a biopsy if there are any concerns about the nature of the lesion. A dermatologist can also offer treatment options, which may include removal if deemed necessary.

4. Consider Psoriasis Management: Since you have a history of psoriasis, it may be beneficial to discuss your overall skin health with your healthcare provider. Managing your psoriasis effectively may help reduce the likelihood of new lesions forming.

5. Follow-Up Care: If you do have the lesion removed, follow the aftercare instructions provided by your healthcare provider to minimize the risk of recurrence.

Conclusion
In summary, the recurrence of your mole after picking it can be attributed to skin regeneration, the type of lesion, and irritation from picking. It’s crucial to avoid further irritation and to consult a dermatologist for a proper evaluation and management plan. They can help determine the best course of action based on your specific situation and skin health history.
