I've had three mildly atypical moles removed by excision surgery. Margins clear. Just wondering, is it often that moles come back? I understand they come back from a shave biopsy but for excision surgeries that went down to the fat tissue are they likely to come back under the scar? Thank you.

Return of a brown spot after mole removal
Once a mole is surgically excised with positive margins, it is unlikely to return. However, if it does return, a prompt visit to your surgeon is warranted.
If a lesion is completely surgically excised and the margins were confirmed to be clear, the lesion should not return.
Do Moles Come Back After Excision
Once cut out and shown to be clear on a pathology examination, such surgically removed moles are unlikely to return.

Recurring moles after excision
Excisional surgeries of moles with microscopically clear margins are very unlikely to recur. Nothing is 100% but this is close. BTW, in my office we will observe the area after the initial shave biopsy of a mildly atypical moles. If any pigmentation recurs in the biopsy site in the future, a very small excision is done (often with a small punch biopsy tool) for a minimal scar.
Do moles come back
First, done in entirety, moles don't come back from shave biopsies - and it removes the least amount of skin needed. No matter the type of excision, sometimes you'll be left with a small edge that may not have been entirely removed, but for an entire mole to return, I'd say less than 3%.
