Wiki Refresher for measurments of lesions

[Sclaborn]

I would like for someone to just remind/refresh me as far as the measurements go in regards to excision of lesions.... Is it add together the largest/greatest diameter of lesion, plus twice the smallest margin?? My brain isn't working today (it is still on vacation I'm afraid)..Thank you in advance!!!!

you take the largest diameter of the lesion and add the margins on each side so twice the margins if you like. that is the excision size which then will yield the code. so a lesion that is 2cm x 4cm with 2cm margins would be an 8cm excision
