Flat Brown Spots on Feet: When to Seek Medical Advice - Dermatology

More Info

---

When it comes to flat brown spots on the feet, particularly those that have been observed to be smooth, non-raised, and of a consistent size (in your case, 0.5mm), it is understandable to feel concerned, especially after researching conditions like melanoma. However, it is important to approach this situation with a clear understanding of the characteristics of skin lesions and the appropriate steps to take.

Firstly, the fact that these spots are flat and have not changed in appearance over time is a positive sign. Melanomas typically exhibit changes in size, shape, color, or elevation, and they often have irregular borders. The spots you described do not seem to fit the classic characteristics of melanoma, especially since they appeared simultaneously on both feet and have remained stable.

That said, it is always wise to remain vigilant about any changes in your skin. The ABCDE rule is a helpful guideline for assessing moles and skin lesions:
- Asymmetry: One half of the mole does not match the other.

- Border: The edges are irregular, ragged, or blurred.

- Color: The color is not uniform and may include shades of brown, black, or even red, white, or blue.

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

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

Since your spots are small, flat, and have not changed, they may not warrant immediate concern. However, if you notice any changes in the future, such as an increase in size, color changes, or if they become itchy or bleed, it would be prudent to seek medical advice.

In terms of seeking medical advice, if you continue to feel anxious about these spots, it may be beneficial to consult a dermatologist for a more thorough evaluation. A dermatologist can perform a dermatoscopic examination, which allows for a more detailed view of the skin lesions and can help in determining whether a biopsy is necessary.
Regarding the option of removal, it is generally not recommended to remove skin lesions unless there is a clear indication of malignancy or if they are causing discomfort. If the dermatologist assesses that the spots are benign, they may suggest a watch-and-wait approach, which is often the best course of action for stable lesions.

In summary, while your concerns are valid, the characteristics of the spots you described do not strongly suggest melanoma. Regular monitoring and consultation with a dermatologist can provide peace of mind and ensure that any changes are addressed promptly. If you experience any new symptoms or changes, do not hesitate to seek medical advice. Remember, early detection is key in managing skin health, and staying informed about your body is always a good practice.
