Forty-six separate renal tumours developed in 36/80 Wistar male rats given a single i.v. dose of streptozotocin (25 mg/kg body wt) to induce diabetes mellitus. Fourteen of the tumours were epithelial in type, 8 were wholly mesenchymal and 24 were largely mesenchymal but also contained epithelial elements. The purely epithelial tumours correspond to the renal adenomas and adenocarcinomas seen in man. The mesenchymal tumours were composed either of undifferentiated spindle cells or of a mixutre of poorly differentiated mesenchyme and epithelial glands. Microscopically, the mixed tumours resembled the nephroblastomas seen in man; both elements appeared to be malignant, but in the absence of metastases this remains unproven. The management of the diabetic state did not influence the incidence of tumours, but insulin appeared to enhance tumour growth.

A chromophobic pituitary adenoma induced on BD IX-rats has been grafted on animals of the same strain. The transplanted tumour takes in 90-100%; it grows at a slow rate (in 7 months after grafting a weight of 7-20 g is attained). Tumour-bearing animals display gigantism and hypertrophy of adrenals; moreover, in 33% of cases, diabetes is observed. With non-diabetic animals, splenomegaly and marked leukocytosis are observed; immature white and red cells are present in the peripheral blood. Spontaneous regression of the tumour never occurs. After surgical removal, tumour regrowth and the formation of metastases are observed. Diabetes is characterised by pronounced hyperglycaemia, glucosuria, polyphagia and polydipsia. Histochemically, insulin cannot be detected in pancreas. Splenomegaly is never observed in diabetic animals. Transplanted adenoma frequently tends to stop growing. No recurrence is observable after extirpation. Spontaneous regression of the tumour sometimes occurs. Gigantism, hypertrophy of adrenals and diabetes are considered as consequences of growth hormone- and ACTH-secretion of the transplanted adenoma. At present the tumour is running in the 8th passage. It did not change its characteristics over a period of 5 years.

Locally recurrent, poorly differentiated carcinoma of the prostate was associated with hypokalemic alkalosis, marked hypernatremia, diabetes mellitus of recent onset, and hyperosmolar syndrome. These findings, with mild hypertension, in the absence of clinical features of Cushing's syndrome, suggested an ectopic ACTH syndrome. Plasma ACTH and cortisol levels were markedly elevated, and failed to suppress in response to either low or high-dose dexamethazone administration. The patient's condition deteriorated rapidly. Autopsy findings included carcinoma extensively infiltrating the prostate with extension to the urinary bladder, and metastases confined to the pelvic nodes and soft tissues. The adrenal glands weighed 23 g and showed diffuse hyperplasia. Extract of the prostatic tumor was analyzed for ACTH and showed approximately 40 times normal plasma levels (or about 4,010 pg/g of tissue); ultrastructural features showed secretory granules consistent with ACTH content of the tumor cells. Such cells were positive when stained for ACTH by peroxidase-tagged immunochemical methods. The case fulfills all established criteria for relating excess corticosteroid production and nonpituitary tumors.

The glucagonoma syndrome occurs in some but not all patients with a benign or malignant islet cell tumor and hyperglucagonemia. Manifestations may include anemia, diabetes mellitus, pruritic skin rash, glossitis, stomatitis, weight loss, diarrhea, flexible fingernails, venous thromboses, low plasma amino acid levels, and coarse folds of the jejunum and ileum. Most patients are postmenopausal women, but men and women ages 40 to 65 have been affected. The course is variable depending upon the nature of the underlying tumor. Twenty-two cases of probable glucagonoma syndrome have been reported; twelve documented with glucagon levels. The hyperglucagonemia results from elevation of the proglucagon and true glucagon immunoreactive fractions of pancreatic glucagon. Management of the rash can be accomplished rarely with topical or systemic antibiotics or corticosteroids. If the tumor is resectable, surgery reverses the syndrome. Patients with metastatic disease have responded to streptozotocin and DTIC.

A 34-year-old man presented with classic glucagonoma syndrome manifested by weight loss, dermatitis, stomatitis, anemia, and mild diabetes mellitus. The diagnosis of glucagonoma was made by light and electron microscopic demonstration of a metastatic alpha cell carcinoma in a liver biopsy specimen. Plasma glucagon concentration was abnormally high. The patient also had symptoms and signs of involvement of the central nervous system. Radionuclide and CAT scans of the brain, negative CSF cytology and myelography excluded the possibility of metastases or other space-occupying lesions. Glucagon was demonstrated in the CSF. We postulate that the neurologic symptoms were due to direct or indirect effect of this hormone on the brain. Following therapy with streptozotocin and 5-fluorouracil, the patient had a subjective and objective clinical and hormonal remission of his disease including amelioration of his neurological impairment.

A 10-year series of patients operated for insulinoma at Sahlgren's Hospital, Gothenburg, is presented. Twelve patients (three men, nine women) aged 26--70 years are included in the material. The patients had a history of recurrent hypoglycemic symptoms of 1 month to 20 years. Hyperinsulinism was established by determinations of blood glucose and plasma insulin in the fasting state. Selective angiography could show the tumor in 3 out of the 12 patients. A through pancreatic mobilization and palpation was performed during operation. Solitary pancreatic tumor was found in 10 patients, and 1 of them had also metastases in the liver. One patient had two tumors, one in the head and one in the tail of the pancreas. In one patient it was not possible to find any tumor at operation. Distal pancreatic resection and splenectomy were performed when the tumor was localized in the body or tail or when no tumor was found. Tumours in the head were excised locally. Microscopy showed insulinoma without malignancy in 10 patients, malignant tumor in insulae with metastases in the liver in 1 patient, and multiple adenomatosis of insulae in the patient without any palpable tumor. The 11 patients with benign disease were examined 1--10 years after the operation and had no signs of hyperinsulinism or of diabetes.

Diabetes mellitus, steatorrhea, cholelithiasis and a tumor distorting the duodenum prompted a work-up for somatostatinoma in a 52-year-old man. The responses of pancreatic B-cells but not of A-cells to nutrient stimuli were inhibited, and growth-hormone release was suppressed, suggesting somatostatin resistance in some target tissues. Plasma somatostatin-like immunoreactivity ranged from 9000 to 13,000 pg per milliliter (normal: 88+/-8, mean +/- S.E.M.) and was distributed in four molecular forms, including free somatostatin. The primary tumor contained 5 microgram of somatostatin-like immunoreactivity per milligram of wet tissue, distributed in three of the molecular forms noted in plasma. Plasma calcitonin was also elevated (4650 pg per milliliter; normal: less than 120). Immunocytochemical studies showed that cells of the primary tumor contained somatostatin and calcitonin but no other peptide hormones. Only somatostatin was present in the metastases. Somatostatin was localized electron microscopically in all secretory granules, irrespective of size and shape, whereas calcitonin was present only within a single subpopulation of small granules in the same cells.

Sixty-five patients operated with total pancreatectomy were reviewed with respect to factors influencing operative mortality and morbidity, long-term survival, and metabolic sequelae. The diagnoses were pancreatic cancer in 58 patients, periampullary cancer in three, cancer of the bile duct in two and leiomyosarcoma of the duodenum and cystadenocarcinoma of the pancreas in one patient, respectively. In nine of the 58 cases with cancer of the caput, the histological examination revealed multicentricity of the tumor. In 44%, there were signs of degeneration and fibrosis in the distal part of the gland. Hospital mortality was 23% for the entire series. After 1970 the hospital mortality was 17%, and among patients operated by senior surgeons especially trained in pancreatic surgery, the hospital mortality was 12% during the whole period. The peroperative bilirubin levels seemed to influence survival time. Among 24 patients operated before 1975 in whom the operating surgeon judged the operation as radical, a five year survival of 21% was recorded. In patients without detectable lymph node metastases, the mean survival time was 25 months. The postoperative exocrine insufficiency and diabetes were possible to control. A blood sugar level above 10 micromol/l was found to significantly decrease the frequency of hypoglycemic attacks. Total pancreatectomy appears to be the surgical procedure preferred when radical treatment is selected.

From 1969-1974 1000 unselected enucleated globes have been examined histopathologically. 277 derive from the University Eye Hospital in Hamburg, 723 from various Eye Hospitals in northern and southern Germany. They originate from 589 men and 408 women, three times the sex was unknown. 86 globes had to be removed from children less than 15 years old. 6 groups of etiologies have been distinguished: trauma (308), histologically confirmed neoplastic disease (281), ocular manifestations of systemic diseases (diabetes mellitus, occlusions of central retinal vessels presumably following generalized vascular disease etc.: 128), "operative ocular disease" (164), primary inflammatory disease (71), miscellaneous (malformations, high myopia, pseudo-glioma and pseudo-melanoma: 48). The etiology "operative ocular disease" consists of 67 primary glaucomas (57 adults, 10 buphthalmus), 41 idiopathic cataracts (7 of these congenital) and 3 primary corneal dystrophies, as well as 53 cases of primary retinal detachment. Among the 281 neoplastic diseases, there are 238 primary intraocular malignant melanomas of the uvea, 18 retinoblastomas, 4 primary reticulumcellsarcomas of the retina, 2 choroidal nevi, 10 intraocular metastases and 9 orbital tumors. 16 enucleations among the 1000 enucleations have been performed for pseudo-gliomas (5 x Coats disease, 5 x persistent primary hyperplastic vitreous, 2 x retrolental fibroplasia, others 4 x). The manifestations of systemic disease are consisting of 68 central retinal vein-occlusions, 30 complications of diabetes mellitus and 10 central retinal artery occlusions as well as 20 other generalized diseases. A primary inflammatory disease led to enucleation 50 times due to an intraocular process, 5 times due to scleritis and 18 times as a consequence of keratitis (including 13 times herpes simplex). As the final clinical cause for enucleation the following categories have been elaborated: secondary glaucomas (416), clinical diagnosis of "tumor" (275), atrophy and phthisis bulbi (118), inflammation (112), acute trauma to 4 weeks after the accident (72), others (7). In conclusion the central role of rubeosis iridis leading to secondary angle closure glaucoma is emphasized. This process presents a challenge to ophthalmologic research. Finally the significance of early surgery for primary angle closure glaucomas and for complete restoration of the anterior chamber after trauma and any intraocular procedure is stressed.

Five patients with cystadenoma of the pancreas were seen during a period of 22 years at this institute. This rare benign tumor occurred predominantly in middle age women, with the presenting symptoms of pain and an epigastric mass, but without a history suggestive of pancreatitis or abdominal trauma. Selective celiac and superior mesenteric antiography is helpful in establishing the diagnosis. If this cystic tumor is not recognized and adequately treated, the surgeon may miss the opportunity for cure. Cystadenoma should be suspected when a cystic mass arising from the body or tail of the pancreas is encountered without evidence of metastases. Although surgical extirpation is the preferable treatment, undue risks should not be undertaken because of the slow growth rate of this benign tumor. Due to the known association of this tumor with other malignant lesions, diabetes mellitus as well as multicystic tumors of the liver and kidneys, these patients should be thoroughtly investigated.
