It is more a question of risk/probabilities of wrong diagnosis, adequate sampling and the standard of care in the community which has some medicolegal implications. There is no reason to reexcise a completeley removed nevus. However, if there is a small risk that the lesion is a melanoma or it is not adequately sampled a recommendation for a reexcision is a reasonable one. Anatomical context will dictate the margin. 0.3 to 0.5 mm is a reasonable albert unnecessary margin in the buttocs but not on the nose. Watch my lecture on Thining in Bets in Dermpedia.

Axel-Could you provide an example please.

Have you seen any of these lesions before?

Thank you Bill.
