Title: Cerebral ganglioneuroblastoma in a golden retriever dog. Author: Kuwamura M, Kotera T, Yamate J, Kotani T, Aoki M, Hori A. Journal: Vet Pathol; 2004 May; 41(3):282-4. PubMed ID: 15133180. Abstract: An 8-month-old Golden Retriever dog was euthanatized because of a large cerebral mass extending from the right frontal lobe to the thalamus that was composed of both mature and immature neuronal cells. The better differentiated cells had abundant eosinophilic cytoplasm with prominent Nissl substance and were generally positive for neurofilament and variably positive for synaptophysin. The generally smaller and less-differentiated cells were infrequently positive for proliferating cell nuclear antigen and were negative for any neuronal and glial markers. No apparent glial differentiation of the immature tumor cells was detected. Based on morphologic and immunohistochemical features, the diagnosis of cerebral ganglioneuroblastoma was made. This neoplasm is very rare in all species, especially in the central nervous system, and has never been reported previously in this site in a dog.[Abstract] [Full Text] [Related] [New Search]
