[Lymphadenectomy from the viewpoint of pathology]

The histopathological examination of lymphadenectomy specimens is an important task in oncological diagnosis. For staging purposes a minimal program of lymph node examination has been defined. It provides a reliable pN classification. The numbers of nodes examined and involved have to be stated in the pathology report. An extended examination program is required to analyse the topography of lymphatic spread and to substantiate the extent of lymphadenectomy for quality assurance.
