title: Malignant jugulotympanic paraganglioma in a dog.
abstract: An invasive malignant epithelial neoplasm was diagnosed as a paraganglioma by light and electron microscopy and immunohistochemically by a positive reaction with anti-neuron-specific enolase. Due to the extensive involvement of the middle ear, a primary origin in the jugulotympanic or jugular paraganglia is suggested.
