Abstract
A 1-day-old male calf presented with clinical signs of severe progressive abdominal distension. Abdominal radiographic and ultrasonic images revealed several loop-like structures in the small intestine, which were indicative of gas retention. Experimental laparotomy was performed. However, the calf died during surgery. At necropsy, a round, well-circumscribed mass (3 × 3 × 2.5 cm) was found in the jejunal wall, and the jejunal lumen was narrowed. The mass was firm and had white to grey appearance on the cut surface. Histologically, the submucosa and the muscle layer were diffusely thickened due to abundance of neural tissues comprising several fascicles of nerve fibres and large aggregates of ganglion cells. Some ganglion cells contained basophilic Nissl substances in their cytoplasm. Immunohistochemically, these cells were positive for S-100 and synaptophysin. Ultrastructural examination revealed that the neoplastic ganglion cells contained dense core vesicles in the cytoplasm. Based on these findings, the neoplastic lesion was diagnosed as ganglioneuroma in the jejunum.

Abstract
Ganglioneuromas are complex tumors that arise in peripheral ganglia and are composed of well-differentiated neurons, nerve processes, Schwann cells, and enteric glial cells. The term ganglioneuromatosis (GN) denotes a regional or segmental proliferation of ganglioneuromatous tissue. This report describes an 8-year-old mixed breed horse with GN in a 25-cm segment of small colon. Grossly, the lesion consisted of numerous sessile to pedunculated nodules extending from the serosal surface. Histologic examination revealed the nodules to consist of fascicles of spindle-shaped cells consistent with Schwann cells, clusters of neurons, supporting enteric glial cells, and thick bands of perineurial collagen. Most of the nodules coincided with the location of the myenteric plexus and extended through the outer layer of the tunica muscularis to the serosal surface. Neuronal processes were demonstrated within the lesion with electron microscopy. With immunohistochemistry neurons were positive for neuron specific enolase (NSE) and S-100 and the Schwann cells and enteric glial cells were positive for S-100 and glial fibrillary acidic protein (GFAP). The pathogenesis of GN is poorly understood. GN, although rare, should be included in the differential diagnosis of gastrointestinal tumors in the horse.

Abstract
A cardiac mass (3 × 5 × 3 cm) was detected at the base between the right auricular wall and right vena cava of a slaughtered 6-month-old female mixed-breed pig during a meat inspection. The tumor comprised infiltrative prominent interweaving fascicles of Schwann cells with Verocay bodies. Moreover, the ganglion cells were scattered or aggregated throughout the neoplastic tissue. The ganglion and Schwann cells had neither cellular atypism nor mitosis. On the basis of the bearing site as well as the morphological and immunohistochemical features, this is the first case of a cardiac ganglioneuroma in a pig.

Abstract
Ganglioneuromatosis (GNM) is a rare condition characterized by the benign proliferation of ganglion cells, nerve fibres and supporting cells of the enteric nervous system. Necropsy examination of a female piglet weighing 4 kg revealed a well-demarcated 20 cm segment of terminal ileum with thickening of the wall. Microscopically, the lamina propria was infiltrated by enteric glial cells and large ganglion cells. Within the submucosal and muscular layers, aggregates of neurons were interlaced by Schwann cells and enteric glial cells arranged in concentric rings. Immunohistochemically, the neurons were weakly labelled for S-100 and neuron-specific enolase, Schwann cells expressed S-100 and vimentin and enteric glial cells expressed glial fibrillary acidic protein and S-100. Pathological and immunohistochemical findings supported the diagnosis of ileal GNM.

Abstract
A 9-year-old female neutered collie-cross dog was presented with a 2-month history of persistent diarrhoea, weight loss and intermittent vomiting. Abdominal ultrasonography revealed one loop of jejunum with a markedly thickened and multifocally hyperechoic wall, without loss of wall layering. Laparotomies were performed for biopsy and resection of affected intestine. Histopathological examination revealed small intestinal ganglioneuromatosis (GN). The dog recovered well from surgery and the diarrhoea resolved. Eleven months later the dog has gained weight and remains asymptomatic. This is the first report of small intestinal GN affecting a mature dog, in which pathology was localized to the mucosal lamina propria and surgical treatment resulted in a successful outcome.

Abstract
In the current study, a case of a cardiac ganglioneuroma with systemic metastases in a cat is described. A 12-year-old male neutered Japanese domestic cat was brought to a veterinary hospital for dysorexia, coughing, vomiting, and diarrhea. Ultrasonography revealed a mass adjacent to the right atrium. The animal died of respiratory failure 1 month after the first visit to the hospital. At necropsy, an oval-shaped white mass 1.5 cm in diameter was observed within the right auricle. Diffusely, the right ventricle was infiltrated and thickened by the neoplastic lesion. Histologically, the mass was composed of 3 types of neoplastic cells: spindle cells, large polygonal cells, and small undifferentiated cells. Immunohistochemically, the neoplasia was positive for neuronal markers such as βIII tubulin, S-100a, and protein gene product 9.5. Ultrastructurally, the large polygonal cells were characterized by abundant cytoplasm that included compressed Golgi cisternae and rough endoplasmic reticula and abundant intermediate filaments. A discontinuous basement membrane surrounded the spindle cells. Metastatic foci were found in the lungs, kidney, pancreas, urinary bladder, and adrenal glands. The morphological, immunohistochemical, and ultrastructural characteristics of the tumor cells were consistent with those of ganglioneuroma. The tumor was presumed to originate from the intramural parasympathetic ganglia in the right atrium.

Abstract
A mass was located in the small intestine of a slaughtered 6-month-old male Landrace-cross pig that had no clinical abnormalities. This egg-shaped well-circumscribed mass was situated in the submucosal and muscular tissue layers and protruded into the lumen. Histopathologically, the tumor comprised discrete or aggregated ganglion and schwannian cells in neuropil-like tissue. Some ganglion cells contained Nissl substance in their cytoplasm. The ganglion cells stained positive for neuron-specific enolase, class III β-tubulin, neurofilament, and synaptophysin; the schwannian cells stained positive for vimentin, S-100 protein, and glial fibrillary acidic protein. The tumor was diagnosed as a ganglioneuroma in accordance with these findings. Here, we have reported detailed immunohistochemical findings in addition to the histopathological features of a swine ganglioneuroma.

Abstract
Ganglioneuroma involving the brachial plexus, paraspinal ganglia, and cervical-thoracic spinal cord was diagnosed in 2 adult cockatiels (Nymphicus hollandicus). Both birds had a chronic 1-year history of ataxia and perching difficulty. At necropsy, each bird had a unilateral, firm, gelatinous white to tan multilobular mass at the thoracic inlet expanding and partially obliterating the brachial plexus and cervical spinal cord. Histologically, the masses were characterized by a locally infiltrative neoplasm comprised of spindloid cells forming streams and sheets with interspersed distinct neuron cell bodies consistent with ganglion cells. The spindloid cell population was immunohistochemically positive for neurofilament protein in one of the birds.
