Concerns About a Changing Mole on Your Big Toe: What You Should Know

Mole on the big toe?

Two years ago, I developed a mole on my big toe, approximately 0.35 mm in size.
Recently, I measured it and found it had grown to 0.5 mm.
I read online that moles on the soles of the feet should be monitored closely, so I went to the hospital for surgical removal and biopsy.
The mole has an oval shape, but the doctor noted some jagged edges around it upon closer inspection.
I later wondered why the doctor didn't use a dermatoscope at that time.
I was very anxious and asked the doctor about the likelihood of it being serious.
He mentioned that most biopsy results are benign.
Can you tell me if a mole like mine, which is oval with a darker center and lighter edges, is considered normal?

Has it been removed? Then just be patient for a few days until the pathology report comes out, right?

When it comes to moles, especially those that change in size, shape, or color, it's essential to approach the situation with caution. The mole you described on your big toe has increased in size from 0.35 mm to 0.5 mm over two years, which is a notable change. While many moles are benign, any changes in a mole's characteristics can warrant further investigation.

The fact that you sought medical attention and had the mole surgically removed for biopsy is a prudent step. Dermatologists often recommend monitoring moles for the "ABCDE" characteristics: Asymmetry, Border irregularity, Color variation, Diameter greater than 6 mm, and Evolving changes. Your description of the mole being oval-shaped with a jagged border raises some concerns, as irregular borders can be a sign of atypical moles, which may require further evaluation.

Regarding your concern about the doctor's decision not to use a dermatoscope, it's worth noting that while a dermatoscope can provide a more detailed view of skin lesions, many dermatologists can make assessments based on visual inspection. However, if there are any doubts, a dermatoscopic examination can be beneficial in determining the nature of the mole.

The biopsy results will ultimately provide the most definitive answer regarding the mole's nature. Most moles are benign, but if the biopsy reveals atypical cells or signs of melanoma, it may necessitate further treatment or monitoring. The appearance of the mole, with a darker center and lighter edges, can sometimes be seen in benign nevi, but it can also be indicative of dysplastic nevi or even melanoma, depending on the specific characteristics.

It's also important to consider the location of the mole. Moles on the soles of the feet can be particularly concerning because they are often less visible and may be more prone to changes due to friction or trauma. This is why there is heightened awareness regarding moles in these areas.

In conclusion, while the majority of moles are benign, any changes in size, shape, or color should be taken seriously. The fact that you have already taken steps to have the mole removed and biopsied is commendable. Once you receive the biopsy results, you will have a clearer understanding of the situation. If the results are benign, regular monitoring of your skin for any new or changing moles is advisable. If there are any concerns or if the results indicate atypical changes, discussing further management options with your healthcare provider will be essential. Always trust your instincts when it comes to changes in your body, and don't hesitate to seek a second opinion if you're unsure about the findings or recommendations.
