Best way to remove a flat mole on the nose? (photo)

Very small flat dark spots can be electrofulgurated (burned) easily and very prescisely. This takes the color out of them and they look like normal skin often.  Sometimes they need a 2nd or 3rd zapping but usually look great afterwards. With a lot of sun these little dark spots will return and can be zapped again in 2-5 yrs if needed. Sincerely,David Hansen,MD

Removal by shave excision or hyfrecator or Erbium/CO2 laser would all be effective and less likely to leave a scar compared to excision.  I would go with the method that your dermatologist feels most comfortable with and is most experienced with.  

From your description and the appearance of the mole on the photograph it appears that a shave removal would be the best way to go. A shave excision is typically the easiest, most cost effective, and
least likely to scar method of removal for these types of moles. With this method the mole is actually
"shaved off" at a level just below the surface of the skin. I would recommend seeing a dermatologic surgeon as they are experts at doing this procedure.
