Hello Xiao K,
Thank you for reaching out with your skin concerns regarding the darkened and thickened areas around your ankles, as well as the mole on your arm. It’s understandable to feel uncertain about these changes, and I’m here to provide some insights that may help you decide whether to seek medical attention.

First, let’s address the darkened and thickened skin around your ankles. This condition could be attributed to several factors, including friction, pressure, or even a skin condition known as acanthosis nigricans, which is characterized by dark, velvety patches of skin. Acanthosis nigricans is often associated with insulin resistance, obesity, or endocrine disorders, but it can also occur in healthy individuals due to friction or irritation. Since you mentioned that the skin is not painful or itchy, it may not be an urgent issue, but it’s still worth monitoring.

Another possibility is that the thickening could be a result of a benign condition such as a callus, especially if you wear shoes that rub against your ankles. Calluses are thickened areas of skin that develop in response to repeated friction or pressure. They are generally harmless and can be managed with proper foot care, including moisturizing and using protective padding.

However, it’s essential to consider that any significant changes in your skin, especially if they are new or have changed in appearance, should be evaluated by a healthcare professional. A dermatologist can provide a thorough examination and determine if any underlying conditions need to be addressed. They may also recommend treatments or lifestyle changes to help manage the condition.

Now, regarding the mole on your arm, it’s crucial to keep an eye on any changes in size, shape, color, or texture. The fact that it is approximately 0.3 cm, round, and slightly raised is not inherently concerning, especially if it has not changed over time. However, the “ABCDE” rule is a helpful guideline for assessing moles:
- Asymmetry: One half does not match the other.

- Border: Edges are irregular, ragged, or blurred.

- Color: Color is not uniform and may include shades of brown, black, or other colors.

- Diameter: The mole is larger than 6 mm (about the size of a pencil eraser).

- Evolving: The mole is changing in size, shape, or color.

If your mole does not exhibit any of these concerning features, it may not require immediate attention. However, if you notice any changes or if it begins to itch, bleed, or become painful, it’s advisable to consult a dermatologist.

In summary, while the conditions you described may not seem urgent, it is always better to err on the side of caution when it comes to skin changes. A visit to a dermatologist can provide peace of mind and ensure that any potential issues are addressed early. They can also offer personalized advice based on your specific situation.

In the meantime, consider keeping your skin moisturized, avoiding tight clothing or shoes that may cause friction, and monitoring any changes in your skin or moles. If you have any further questions or concerns, don’t hesitate to reach out.
