Zollinger-Ellison Syndrome in a 12-year old castrated male European Shorthair cat is described. The clinical symptoms were
vomiting
, weight loss, listlessness and alternating diarrhoea and obstipation. An endocrine tumour near the pancreatic duct had metastasised to the liver. Many duodenal ulcers were present. Immunohistochemistry revealed cells positive for gastrin and
neuron-specific enolase
(
NSE
) scattered throughout the tumour.

Three patients suffering from an absence of the enteric nervous system are reported. Two sisters presented with severe
vomiting
shortly after birth and dilatation of the intestine proximal to a stenosis. There was an absence of the enteric nervous system throughout the entire length of the intestine distal to the duodenum. A boy presenting an ileus was found to suffer from an aganglionosis of the entire colon. There was also an absence of neuronal bodies and nerve fibers in the small intestine. The final diagnosis was made by histochemical and immunocytochemical stains for acetylcholinesterase, lactate hydrogenase,
neuron-specific enolase
, protein S-100, and substance P. In the literature, 13 other patients have been reported. On the basis of differences of symptoms, incidence, sex ratio, genetics, and, presumably, pathogenesis between absence of the enteric nervous system and aganglionosis, it is assumed that the two diseases are separate entities.

We evaluated the clinico-pathophysiological features of three patients with acute autonomic and sensory neuropathy (AASN) who were followed for over 3 years. Signs of an autonomic disturbance including
vomiting
, anhidrosis, urinary disturbances, orthostatic hypotension and reduced coefficient of variation of the R-R interval on electrocardiography gradually improved about 1 year after onset. However, all three exhibited severe generalized sensory impairment for all modalities with the development of persistent sensory ataxia. No sensory nerve action potentials could be elicited and no somatosensory evoked potentials could be obtained. Sural nerve biopsy revealed severe axonopathy. In two patients, a high-intensity area was observed in the posterior column of the spinal cord on T2*-weighted axial magnetic resonance images. The level of
neuron-specific enolase
in cerebrospinal fluid was markedly elevated in two patients, indicating spinal nerve root or sensory neuron damage. Motor nerve function was well preserved in all patients. Our findings suggests that the major lesion in patients with AASN, particularly those with a sensory deficit, is present in the dorsal root ganglion neurons, that is there is a ganglioneuronopathy.

We report a case of microcystic (glycogen-rich) adenoma of the whole pancreas with coexistent pancreatic low-grade malignant islet cell tumor in a 29-year-old woman. She complained of nausea,
vomiting
, and growing abdominal mass. Abdominal computed tomography showed multiple cysts in the whole pancreas and a calcified solid mass in the pancreatic head. A Whipple's operation and total pancreatectomy with splenectomy was performed to treat pancreatic cystic neoplasm. The pancreas was entirely replaced by variable-sized, multilocular cysts, which were lined by a flattened-to-cuboidal glycogen-rich epithelium. Furthermore, in the head of the pancreas, a focal yellowish solid mass showed a positive reaction for chromogranin A and
neuron-specific enolase
. Careful examination of the pancreas is warranted in cases of microcystic adenoma to rule out a possible coexistent pancreatic malignancy.

An intestinal carcinoid with multiple metastases was identified in a 5-year-old male Shih Tzu with a clinical history of anemia, fatigue, anorexia,
vomiting
, intermittent diarrhea, intestinal bleeding, and progressive emaciation. There was a yellowish-white mass 15 mm in diameter in the anterior jejunum and white nodules consistent with metastases in many organs. Histopathologically, the mass consisted of neoplastic cells arranged in lobules, trabeculae, or closely interdigitating islands of cells. Neoplastic cells were generally polygonal with round hyperchromatic nuclei, modest amounts of eosinophilic cytoplasm, and eosinophilic cytoplasmic granules. Mitoses were common. Rosette formations of tumor cells were apparent in metastatic tumors. Immunohistochemically, tumor cells stained positive for cytokeratin 13, synaptophysin, protein gene product 9.5,
neuron-specific enolase
, chromogranin A, calcitonin gene-related peptide, serotonin (5-HT), and Leu-7. Serum 5-HT concentrations for this dog were increased 10-fold compared with those of normal dogs. All findings were consistent with a diagnosis of a malignant intestinal carcinoid.

Plexiform schwannoma is a benign peripheral nerve sheath tumor composed exclusively of schwann cells arranged in a plexiform pattern. Most plexiform schwannomas are skin tumors and there has been only one case report of this tumor originating in the colon. We describe herein the first known case of plexiform schwannoma of the small intestine occurring without any relationship to schwannomatosis or neurofibromatosis. A 57-year-old man presented with a short history of abdominal pain,
vomiting
, and bloody stool after each meal. Jejunography demonstrated multiple nodular tumors in the small intestine. We resected the small intestine laparoscopically. The tumors consisted of multiple white nodules in the submucosal and subserosal layers. Microscopic examination revealed that each tumor was composed mainly of Antony A tissue, compatible with conventional schwannoma. Immunohistochemically, the tumors were positive for S-100, vimentin, and
neuron-specific enolase
, and negative for HHF35, Alpha-SMA, and c-kit. No evidence of recurrence has been found in 38 months of follow-up.

Medulloblastoma is a malignant invasive embryonal tumor of the cerebellum with preferential manifestation in children. The peak of occurrence is seven years of age. Seventy percent of medulloblastomas occur in individuals younger than 16. In adulthood, 80% of medulloblastomas arise in the 21-40 years age group. A 48-year-old male patient was admitted to the hospital with complains of headache, ataxia, morning
vomiting
and difficulty in speech was operated with the diagnosis of presence of mass of 4 x 7 cm size retaining a diffuse homogenous contrast in the posterior fossa. The diagnosis of desmoplastic medulloblastoma was given after histopathological examination. Immunohistochemical examination revealed that neoplastic cells showed staining with
neuron-specific enolase
and synaptophysin but not with glial fibrillary acidic protein. This lesion showed nodular, reticulin free-zones (pale islands) surrounded by densely packed, highly proliferative cells. The pale regions within the tumor did not contain reticulin fibers. Desmoplastic medulloblastoma is encountered especially in adulthood. This type of tumor rarely occurs beyond the fifth decade of life. We present a case of desmoplastic medulloblastoma in a 48-year-old male.

Ten dogs with neuroendocrine carcinoma of the liver were selected for inclusion in the study. Clinical signs were anorexia (7),
vomiting
(5), polydipsia/polyuria (3), icterus (2), lethargy (2), weight loss (2), paresis (1), ataxia (1), weakness (1), collapse (1), and urinary tract infection (1). Hematologic and biochemical abnormalities included anemia (2/8), leukocytosis (4/8), high liver enzyme activity (serum alkaline phosphatase, 7/9; alanine transaminase, 7/9; aspartate transaminase, 8/9), and high total bilirubin (6/9). Grossly, the tumors were diffuse, involving all liver lobes in six dogs, and two dogs had various-sized nodules in addition to diffuse involvement. Histologically, there were eight tumors with solid or trabecular pattern (group A), one tumor with cords or rows of neoplastic cells (group B), and one tumor with multiple rosette-like structures (group C). Immunohistochemical studies revealed that all 10 neoplasms were positive for at least one of the endocrine markers used:
neuron-specific enolase
(NSE; 8/10), synaptophysin (5/10), and chromogranin-A (3/10). A panel of NSE, chromagranin-A, and synaptophysin detected 100% of the tumors in our series. Electron microscopy confirmed the diagnosis by the presence of intracytoplasmic neurosecretory granules in the two examined cases. Our results show that neuroendocrine markers commonly used in humans can be used for the diagnosis of hepatic neuroendocrine carcinoma in dogs, preferably a panel of synaptophysin, chromagranin-A, and NSE because chromogranin-A alone is not as useful in dogs as in humans.

Hepatobiliary neuroendocrine carcinoma was diagnosed in 17 cats in a period of 10 years. Seven tumors were of intrahepatic origin, one of which was a composite containing components of epithelial and neuroendocrine carcinoma. Nine tumors were of extrahepatic origin, and one tumor was located in the gall-bladder. The cats were adult and geriatric, and the male : female ratio varied according to tumor group. Hepatomegaly, anorexia, weight loss, and
vomiting
were the most common clinical signs observed in the cats with hepatic neuroendocrine carcinoma. The cats with extrahepatic neuroendocrine carcinoma showed these signs plus icterus (5/9) and high concentrations of hepatic enzymes. Histologically, the hepatic neuroendocrine carcinomas had two patterns, one with acinar structures separated by vascular stroma lined by cuboidal or columnar cells and the other solid with groups of anaplastic cells separated by vascular stroma. The composite tumor consisted of both bile duct carcinoma and neuroendocrine carcinoma. The extrahepatic neuroendocrine carcinomas and the gallbladder neuroendocrine carcinoma were characterized by solid sheets or groups of round to oval cells with vascular or fibrovascular stroma. Immunohistochemical examination of 10 of the neuroendocrine carcinomas revealed that all 10 stained with
neuron-specific enolase
; one bile duct carcinoma and the gallbladder carcinoma stained with chromogranin; four of five bile duct carcinomas and the gall bladder carcinoma stained with synaptophysin; and one bile duct carcinoma stained with gastrin. One cat with hepatic carcinoma had duodenal ulcer; in this cat, ultrastructural studies showed neurosecretory granules leading to the diagnosis of Zollinger-Ellison syndrome. In four cats in which necropsy was permitted, carcinomatosis (4/4), lymph nodes (4/4), lungs (2/4), and intestines (1/4) were the metastatic sites. Fourteen of the 17 cats were euthanatized during or immediately after surgery.

Adrenal abscess is a rare disease in the neonatal period. The classical symptoms are abdominal mass, anaemia and prolonged jaundice which are associated with fever,
vomiting
and feeding difficulties. The authors present the histories of two mature, male newborns with adrenal hemorrhage, where the size of the masses increased progressively and finally adrenal abscesses were developed. The first case showed the classical symptoms of adrenal abscess, however, the antibiotic treatment led to complete remission of the symptoms and laboratory infectious markers, therefore the baby was discharged. In a few day later he became septic and was admitted again. This time he was operated on and a large abscess was evacuated, which contained about 60 ml of pus. After this intervention multi-organ failure developed, but due to the intensive therapy the baby recovered. In the second newborn the increasing adrenal hemorrhage was accompanied by elevated infectious markers despite of the different antibiotic treatments, however, he showed no clinical signs of infection. Because of the discrepancies between the clinical and laboratory findings and also the imaging studies the possibility of neuroblastoma has also arisen. Urinary vanillylmandelic acid excretion was normal, but elevated
neuron-specific enolase
levels were measured. Surgical exploration was performed, pus was drained from the mass and anaerobic Bacteroides fragilis was cultured, therefore metronidazole therapy was started. After that the baby fully recovered.
