okay
1.if you have a mole or wart etc if its benign looking but not 100 % sure ,you need a histological input you do a narrow margin.
2.if you have a lession thats looking slightly more suspicious but going more in favour of bening lession you would do a clear margin eg-bcc
3.if a lession has strong suspicion of malignancy you would do a wide excission.1st and depending on breslows thickness you go and do a wider excission later on .
4.punch biopsy,using a pen like instrument its got a circular blade at the tip(either 3mm/6mm diameter) you press down on the area (that you want to biopsy) (ofcourse after Local anesthetic infilteration )you get a chunk of tissue, you would do this mostly for inflamatory/autoimmune lessions eg psoriasis phemphigus,lichen, etc very rareley for malignant lessions (for eg a large scc in the border of marjolins ulcer or chronic scar (you are suspecting malignant change)
hope this makes sense...
