*A slice is cut-off the penis at the site of the resection margin. This slice is then divided into left and right with a sagittal cut. Each portion (left and right) is sectioned with parasagittal cuts such that it is submitted as an on edge margin. | *A slice is cut-off the penis at the site of the resection margin.
