Figure 13. Histopathological preparation of the specimen. The specimen is sliced after Formalin fixation and the axial tissue slices can either be sampled or embedded whole into large cassettes. Extent of tumour spread (arrowheads) as well as distance to the closest non-peritonealized circumferential resection margin (double arrow) can then be assessed by the pathologist on the haematoxylin and eosin section.
