Undifferentiated ganglioneuroblastoma in a sheep.
Ganglioneuroblastoma, presumably originating from the adrenal medulla, was found in an 18-month-old sheep. Histologically, the tumour was mainly composed of undifferentiated neuroblasts with neuropil and occasional ganglion cells. The morphological and immunohistochemical features with respect to intermediate filament proteins and the neuroendocrine nature of the tumour are described. The neoplastic cells were positive for neuron-specific enolase, synaptophysin and vimentin.
