Abstract

Many advances have been made in the characterisation of primary liver tumours in humans, in particular relating to the identification and role of hepatic progenitor cells, resulting in a new classification. The aim of the present study was to investigate the presence and relative frequency of morphological types of canine primary hepatic neoplasms and to determine whether a classification similar to the human scheme can be applied to these canine neoplasms. Canine primary liver tumours (n=106) were examined histologically and with the immunohistochemical markers keratin 19, HepPar-1, epithelial membrane antigen/mucin-1, CD10, neuron-specific enolase and chromogranin-A. Eleven nodular hyperplasias and 82 tumours of hepatocellular origin were diagnosed. The latter were subdivided in hepatocellular tumours with 0-5% positivity for K19 (n=62), which were well differentiated and had no evidence of metastasis, tumours with >5% positivity for K19 (n=17), which were poorly differentiated and had intrahepatic and/or distant metastasis, and a scirrhous subgroup (n=3) with an intermediate position with regard to K19 staining and malignancy. Ten cholangiocellular tumours (nine cholangiocellular carcinomas and one cholangiolocarcinoma) were diagnosed and all had intrahepatic and/or distant metastases. Three neuroendocrine carcinomas were also diagnosed. Histopathological and immunohistochemical examination of canine primary hepatic neoplasms can differentiate hepatocellular, cholangiocellular and neuroendocrine tumours, in accordance with the most recent human classification system.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
