Fig. 1 Radical prostatectomy specimen examined with the whole mount technique. The contoured areas represent cancer and its pattern of spread. The main part (ie, body of the “crab”) of the tumor nodule is in the left posterolateral aspect of the peripheral zone (sections 2 and 3). The contoured areas shown in the other sections (sections 1 and 4) (distance between adjacent sections or thickness of the tissue slices: 3mm; distance between the tumor contained in these areas and the main part of the tumor is <3mm) do not represent additional separate nodules but peripheral extensions or “tentacles” of the tumor (a peripheral nodule is considered part of the main tumor nodule when the distance between the two is smaller than the thickness of the tissue slices).
