The glucagonoma syndrome is characterized by a necrolytic migratory erythematous rash, angular stomatitis, painful glossitis, a normochromic normocytic anemia, mild diabetes mellitus, weight loss, a tendency to thrombosis, and neuropsychiatric disturbances. The diagnosis is made by finding a high plasma glucagon concentration in the absence of any other cause, such as renal failure or severe stress. A pancreatic alpha-cell tumor can be identified and stained by immunocytochemistry with glucagon antibodies. Optimal treatment is surgical removal, but approximately 50 percent of the tumors have metastasized by the time of diagnosis. Since the tumor is slow-growing, remission can be obtained by hepatic artery embolization to shrink hepatic secondaries or by shrinkage, in about 10 percent of patients, with the combination chemotherapeutic regimen of 5-fluorouracil and streptozotocin. The rash frequently responds to administration of zinc, a high-protein diet, and control of the diabetes with insulin. Alongside the alpha cell in the islets of Langerhans is the D-cell, which produces somatostatin and may well act physiologically as a paracrine inhibitor of glucagon release. A newly developed, long-acting somatostatin analogue, SMS 201-995, which the patient can self-administer as a subcutaneous injection, has proven effective in suppressing glucagon secretion from glucagonomas and, in some cases, causing remission of clinical symptoms.

Aroclor 1254, at a dose level of 280 micrograms/kg body weight equivalent to 200 micrograms/kg/day, was given 5 days per week to rhesus monkeys over a 27 to 28 month period. Terminal clinical signs of varying severity included fingernail detachment, exuberant nail beds, weight loss, stomatitis and normocytic anemia. At necropsy the bone marrow was hypocellular with increased M:E ratio and cytoplasmic vacuoles in erythroid precursor cells. Histopathologic lesions included dilatation of the tarsal gland ducts, atrophy or absence of splenic and lymph node germinal centers, bone marrow depletion, gingival erosion and ulceration, moderate mucinous hypertrophic gastropathy with cystic dilatation of occasional gastric glands, hepatocellular enlargement and necrosis, hypertrophy of biliary duct epithelium, hyperplasia of biliary ducts, hypertrophy of the gall bladder epithelium, and an equivocal increase in the number of lysosomes in thyroid follicular epithelial cells. PCB tissue concentrations were lowest in brain and highest in blood. The results suggest that severe potentially fatal PCB toxicity can develop in rhesus monkeys following ingestion of Aroclor 1254 at 200 micrograms/kg/day for a period of 27 months or longer.
