The illusion of conventional histological resection margin control

Abstract

An advantage of surgical treatment for basal cell carcinoma (BCC) over other therapeutic options is the possibility of histological margin control. The general understanding is that only 1‐2% of the actual margins are checked histologically using the 'bread loaf' or step sectioning technique for conventional excision specimens, but the percentage of resection margins that are microscopically evaluated have not actually been quantified to date. [1, 2] This study's objective was to calculate the mean percentage of resection margins of BCC excision specimens that is histologically evaluated.
