Welcome to icliniq.com.
I have gone through the image (attachment removed to protect patient identity). It is a very small papular lesion at present.
It does not need a biopsy at present.
But you might need biopsy if there is:
1. Change in color and irregular surface.
2. Increase in the size of the lesion.
3. Irregular margins.
5. Bleeding, crusting, or oozing.
At present, a test like dermoscopy would help to see the morphology of the lesion. Knowing your past history keep checking on the lesions.
