Figure 3: (a) WPOI 5 showing tumor satellites with more than 1 mm distance between them. (b) To measure DOI, the basement membrane is identified, and an imaginary line is drawn across the tumor. A vertical or plumb line extends to the deepest part of the tumor, which represents the DOI. (c) Perineural invasion showing tumor cells wrapped around the perineurium. (d) Microscopy of a resected margin showing the India ink
