Sorry, I meant knowledge about moles is restricted since we do not come across it as a problem in the tropics.
A mole regrown after removal will show atypia.A dysplstic mole sometimes show severe atypia.There is lot of confusion about nomenclature,but this is not a melanoma.However your consultant may like to remove it with a border.My knowledge about melanomas are restricted,but this is the baseline and the broader picture.Do get the expert column reply.
