Gangliocytic paraganglioma is an extremely rare benign neurogenic tumor nearly exclusively located in the second portion of the duodenum, also the most common site of duodenal diverticula. A case is reported of a gangliocytic paraganglioma presenting in a 65-yr-old woman with a 1-yr history of postprandial cramping abdominal pain culminating in a single episode of melena leading to laparotomy. The tumor was identified with difficulty by endoscopy following negative barium studies. Histologically, the tumor is composed of carcinoid-like cells admixed with varying numbers of ganglion cells in a substratum of neuroid spindle cells. The epithelioid cells contain argyrophilic cytoplasmic granules confirmed by electron microscopy to be dense core membrane-bound secretory granules. Review of the literature suggests the tumor described is typical both clinically and pathologically of gangliocytic paraganglioma of the duodenum, except for its unprecedented occurrence in association with a duodenal diverticulum.

Mesenteric ischemia associated with carcinoid tumors often presents with nonspecific abdominal pain and is usually due to mesenteric branch artery occlusion caused by elastic vascular sclerosis. Mesenteric ischemia was defined by the operative findings of cyanosis or infarction. Eleven patients with intraabdominal metastatic carcinoid tumor were evaluated by angiography. Angiographic narrowing and occlusion of multiple peripheral jejunal and ileal intramesenteric branch arteries was present in 3 patients with mesenteric ischemia, but also occurred in 5 of 8 patients without mesenteric ischemia. Other angiographic abnormalities included staining of the primary tumor (5) or metastases (6), tenting of small mesenteric vessels (5), and occlusion of draining mesenteric veins (2). We conclude that in patients with midgut carcinoid tumors, angiographic narrowing and occlusion of peripheral mesenteric arteries most likely represents elastic vascular sclerosis, is indicative of mesenteric invasion of tumor, but correlates poorly with the presence of ischemia in the subtended bowel. Alternatively, a normal selective arteriogram should exclude mesenteric ischemia as the cause of abnormal pain.

Twelve duodenal carcinoid tumours are presented, 4 of them located in the ampulla. Symptoms included the Zollinger-Ellison syndrome (4 patients), the carcinoid syndrome (1 patient), mechanical obstruction (3 patients), bleeding (1 patient) and abdominal pain (1 patient). Two further tumours were detected by chance. Three patients with the Zollinger-Ellison syndrome had additional endocrine tumours characteristic of the MEN I syndrome. In 2 of them the duodenal carcinoids were of very small size and were multiple. They were observed in close proximity to focal areas of endocrine cell hyperplasia. Immunohistochemical investigations showed gastrin and somatostatin to be the predominant polypeptide hormones produced by these tumours. No somatostatinoma syndrome was encountered. In half of our cases additional production of insulin, VIP or even calcitonin in smaller amounts was found. Two of our patients had cutaneous manifestations of von Recklinghausen's disease and in both of them the carcinoid was located in the ampulla. One of these patients also had a pheochromocytoma.

Two patients with neurofibromatosis and somatostatinoma are described, one patient in addition having a parathyroid adenoma diagnosed post mortem. The other patient had a partial somatostatinoma syndrome with diabetes, abdominal pain and cholelithiasis. The tumour was diagnosed preoperatively and metabolic studies demonstrated mild diabetes mellitus apparently due to suppression of insulin secretion by somatostatin, since oral glucose tolerance returned to normal post-operatively despite hemipancreatectomy. The tumour also secreted gastrin. There are now 18 reported cases of neurofibromatosis and duodenal carcinoid tumours which makes a genuine association between these two conditions very likely. With the present two cases, seven of the carcinoid tumours in this group have been positively identified as somatostatinomas. The histological finding of psammoma bodies is important in the diagnosis of duodenal somatostatinomas.

Carcinoid tumors are the most frequent gut neuroendocrine tumors accounting for more than 50% of all tumors of the gastroenteropancreatic (GEP) axis. These tumors appear to derive from a stem cell line capable of differentiating into a variety of malignant cells that secrete many different peptides and amines. The symptoms of carcinoid tumors are often non-specific, vague abdominal pain that may precede the diagnosis by a median of 9 years. Carcinoid syndrome occurs in less than 10% of patients. We evaluated the effects of SMS 201-995 in 14 such patients, 12 with diarrhea, 8 with flushing, 3 with wheezing, one with tricuspid valve incompetence, 6 with facial telangiectasia, 3 with a pellagra type dermatosis and one with myopathy. Diarrhea was abolished or significantly reduced in 83%, flushing in 100%, wheezing in 100%, and myopathy improved in the one patient. Blood serotonin was resistant to change, urine 5HIAA fell in 75%, and most gut neuropeptide hormones apart from somatostatin were suppressed. Tumor growth appeared to be slowed in 2/3 of cases treated for up to 4 years. The analog of somatostatin appears to be a useful addition to the therapeutic armamentarium for carcinoid tumors and the symptom complex.

Carcinoid tumours in Auckland diagnosed during 1976-87 have been reviewed retrospectively. Eighty-three patients with carcinoid tumours were seen during this time (56 appendiceal, 11 small bowel, two colorectal, 10 pulmonary and four other). Three patients had carcinoid syndrome. The most common presentation for appendiceal carcinoid was acute appendicitis. The most common presentations for pulmonary lesions were incidental findings on chest X-ray, recurrent chest infection or haemoptysis, while bowel lesions presented with abdominal pain or rectal bleeding. Following resection, 53 of 56 appendiceal patients were alive and well (two died from other causes) and 10 of 10 pulmonary carcinoids were alive and well. In contrast, both patients with colorectal carcinoid died from their disease within 1 year, and, of the patients with small bowel carcinoid, one died of the disease and more than half of the remainder are alive with metastatic spread and symptoms at the time of study. The most important prognostic variables governing outcome were anatomical site of the primary lesion and the state of the histological margins following resection.

As a broad generalization, there appears to be little intrinsic difference in the biological behaviour of the common malignant liver tumours in respect of presentation, clinical course, clinical features and prognosis. Whatever the tumour's origin, patients present with some combination of abdominal pain, hepatomegaly, weight-loss and general malaise and death occurs within 3 years of the onset of symptoms. It is the state of the non-tumorous liver (cirrhotic/non-cirrhotic) and the anatomical site of the tumour (as with hilar cholangiocarcinomas) that are responsible for any significant differences. Metastatic carcinoid tumours, epithelioid haemangioendotheliomas, stage IV-S neuroblastomas and the fibrolamellar variant of HCC are exceptions to this rule with a genuinely better prognosis.

A 65-year-old woman visited our hospital, complaining dizziness and abdominal pain. Positive fecal occur blood and an iron-deficiency anemia were found. An investigation of the GI tract was performed, and enteroclysis revealed three stenotic lesions in the ileum, the most distal one having an irregular edge. A superior mesenteric angiogram showed tumor stain and encasement in the ileal region. On laparotomy, a large tumor and multiple stenosis were found in the ileum. Histological examination of the resected specimen confirmed the diagnosis of a carcinoid tumor and healed tuberculosis of the ileum.

Antineoplaston A10 injections were administered to 18 patients diagnosed with 19 types of neoplastic disease. The patients' diagnoses included: adenocarcinoma of the rectum and colon, Stage IV (8 cases); adenocarcinoma of the pancreas (4 cases); adenocarcinoma of the breast, Stage IV (3 cases) and single cases of adenocarcinoma of the lungs, Stage III; adenocarcinoma of the stomach, Stage IV; chondrosarcoma of the nose and right maxillary sinus; and carcinoid. The treatment was administered from 52 to 640 days. The highest dosage taken was 2210.5 mg/kg/24 h. Most of the patients were taking from 206.9 to 387.1 mg/kg/24 h. The treatment was associated with minimal side-effects including febrile reactions, muscle and joint pain, muscle contraction in the throat, abdominal pain of short duration and single incidences of nausea, dizziness and headache. Desirable side-effects included increase of platelet count and white blood cell count. Objective response to the treatment was noticed in 8 patients including one patient diagnosed with intraductal carcinoma of the breast, Stage IV, 2 patients with adenocarcinoma of the sigmoid, Stage IV, 1 patient with adenocarcinoma of the rectum, Stage IV, 2 patients with adenocarcinoma of the pancreas, 1 patient with adenocarcinoma of the lung, Stage III, and 1 chondrosarcoma.

This is a report of a 12-year-old boy having gastric duplication with foci of carcinoid. He complained of right abdominal pain. Physical examination showed a cystic mass in the right abdomen. It was excised operatively. The mass was a duplication cyst composed of gastric mucosa with a muscle layer. Foci of carcinoid was detected in the muscle layer. The tumor cells involved nerve fibers but did not extend to the subserosa. Postoperative blood serotonin and histamine levels were normal. The patient is healthy without signs of recurrence 17 months after operation. This is the second case of gastrointestinal duplication with foci of carcinoid. The findings indicate that careful histologic examination is necessary to determine the exact nature of the cyst.
