What Type of Doctor Can Help my Knuckle Scar Removal Procedure?

I know you were not happy with the recommendation from the prior dermatologist, but I would recommend getting a second opinion.  There are several lesions this could be such as a dermatofibroma, knuckle pad, scar, etc and thus perhaps a consult with a derm that you feel comfortable with would be best.

 

First, think about getting the optimal result and not a quick fix. Has the lesion ever been biopsied? It represent a scar or a lesion formation at the site of the trauma. This can best be appreciated by examination. A plastic surgeon or hand surgeon who addresses soft tissue matters would be best suited to evaluate the mass.
