The clinical and pathologic features of 43 primary adenacarcinomas of the small intestine (32 jejunal and 11 ileal) are reported. Seventy-four percent of the patients presented with partial or complete small bowel obstruction, 56% complained of abdominal pain, 37% had symptoms of anemia (weakness, easy fatigability), and 35% had lost weight. Anemic hemoglobin levels occurred in 69%, and a palpable abdominal mass in 25%. Treatment consisted of a "curative" or "palliative" resection, or a bypass procedure. Seventy-nine percent of the tumors showed an annular, constricting pattern, while the remaining 21% had a predominantly fungating or polypoid appearance. Three individuals currently free of clinical recurrence have been followed less than 5 years. Of the remaining 40 patients, a 5-year cure was achieved in 11 (28%), including 6 (15%) who at present have no recurrence and 5 (13%) who subsequently died of other causes. Within 5 years, 28 of these 40 patients (70%) were known or presumed dead tumor, and 1 had succumbed to other causes (2%). Various pathologic features were correlated with the clinical course. Documented lymph node metastasis proved to be the most valuable prognostic finding, 88% of these individuals dying of tumor, as contrasted to 45% of those with tumor-free nodes. A few cases of superficially invasive carcinoma found in an otherwise benign adenomatous lesion had a good prognosis when symptoms were produced mainly by the adenoma, the carcinoma being a relatively minor component.

A 56-year-old woman with symptoms of weakness, visual blurring, and sweating underwent diagnostic studies to evaluate the etiology of her hypoglycemia. Fasting hypoglycemia was never documented; in diagnostic studies performed during her two hospitalizations and several outpatient glucose tolerance tests, the lowest fasting plasma glucose recorded was 56 mg/dl. The patient displayed exaggerated plasma insulin responses following oral glucose (peak response: 447 muU/ml at 30 min) and following 1 gm of iv tolbutamide (peak response: 719 muU/ml at 5 min) with symptomatic profound hypoglyceria during both tests. Basal per cent proinsulin was elevated at 49% (normal range 5-22%). Throughout a 72 h fast, values for plasma glucose, insulin, and glucose/insulin ratios were all within the normal range. During the infusion of exogenous insulin (0.1 U/kg for 60 min) serum C-peptide reactivity suppressed to less than 1.3 ng/ml when the plasma glucose fell below 40 mg/dl representing normal suppression. At surgery, a pancreatic beta cell adenoma was found and removed. This patient represents the uncommon circumstances in which stimulation tests with tolbutamide and glucose were more helpful in establishing a preoperative diagnosis than were the suppression tests.

A 46-year-old female presented with a three year history of progressive weakness. Asymptomatic apart from proximal myopathy, multi channel screening and radiological features indicated primary hyperparathyroidism with severe metabolic bone disease. Removal of a parathyroid adenoma led to improvement of muscle strength and regression of bony and metabolic changes.

A study is presented of 14 patients with hyperparathyroid crisis treated at the Massachusetts General Hospital between 1964 and 1978. These patients showed diverse clinical manifestations that were indistinguishable from those in patients with pseudohyperparathyroidism. Their symptoms varied from progressive fatigue, malaise, and weakness to those related to the gastrointestinal and urinary tracts. The one biochemical alteration commonly found among these patients was the rapid increase in the serum calcium. There was a concomitant rise in the BUN in 50% of the patients and in the creatinine in 80%. The diagnosis was established by an elevated immunoreactive parathyroid hormone (PTH) level in all eight patients (100%) who had the radioimmunoassay; by the presence of subperiosteal resorption of the phalanges in six of the eight patients (75%); and in three of four patients (75%) by the loss of the lamina dura of the teeth. The 12 patients who had surgery all survived; the two who did not died. Thirteen patients (93%) had a neoplasm--an adenoma in 12 and a carcinoma in one. One patient had hyperplasia (7%). Nine patients (64%) received hypocalcemic drug therapy. The serum calcium temporarily fell to 12 mg/100 ml in five patients (56%) but failed to budge in four (44%). Simultaneous treatment with saline infusion, furosemide and with hypocalcemic drugs over a prolonged period compounded the difficulty at operation by increasing interstitial edema. Our findings from this study show prompt surgical intervention as the ideal treatment for hyperparathyroid crisis, preferably, within 72 hours of the acute onset of symptoms.

The clinical features of primary hyperparathyroidism have been discussed. A case has been reported which presented many of the classic signs of the disease, including renal stones, duodenal ulcer, muscle weakness, and a swelling in the jaw. The problems of diagnosis and localization of adenoma have been discussed, and reference has been made to new diagnostic techniques using radiologic control and selective venous catheterization. The literature has been briefly reviewed and the importance of early diagnosis and treatment has been stressed.

We report the case of a 33-year-old woman who was operated on with the diagnosis of primary hyperparathyroidism (PHP) in 1986. She had bone disease and slight hypercalcemia. Two parathyroid glands were removed with a lack of clinical improvement. Subsequently, the serum calcium levels were normal with occasional slight increases. Depressed phosphorus values and elevated alkaline phosphatases and PTH levels were also present, associated with severe bone involvement and muscular weakness. A second cervical exploration performed in 1989 disclosed only a normal parathyroid gland, which was not removed. In 1990, a thoracic CT scan showed the presence of a 1 cm mediastinal nodule close to the great vessels. A thoracotomy was performed to remove this nodule, which proved to be a parathyroid adenoma. After surgery, the patient presented with a "hungry bone" syndrome, characterized by very low levels of calcium, phosphorus and magnesium, which required enteral and parenteral calcium and magnesium supplements, plus dihydroxyvitamin D. The association of normocalcemia and intermittent hypercalcemia with severe bone disease is very rare, as is the presence of a mediastinal adenoma. This could explain the difficulty in the diagnosis in this case.

A 69-year-old female patient had been treated with glucocorticoid for eight years because of rheumatoid arthritis. She showed characteristic Cushingoid features such as central obesity, moon face, and fragility of skin and vessels. She was disabled because of spinal compression fracture and muscle weakness. The blood pressure was 186/100 mmHg and the laboratory tests revealed serum K: 2.8 mEq/l, WBC: 15, 510/mm3, total cholesterol: 310 mg/dl. These suggested that she had iatrogenic Cushing's syndrome. After discontinuation of glucocorticoid, however, the serum cortisol level remained high. This fact prompted us to conduct further examinations for Cushing's syndrome. Oral dexamethasone administration did not suppress the plasma cortisol level and a left adrenal adenoma was found on abdominal CT scan. Because of the presence of bleeding diathesis, operation for adenoma was contraindicated. Though we tried to treat her with metyrapone, trilostane or opeprim (OP'-DDD), we had to abandon specific treatment because of severe side effects such as acute adrenal dysfunction and gastrointestinal problems. Decrease in the endogenous cortisol level after metyrapone treatment caused exacerbation of symptoms of rheumatoid arthritis. This is a peculiar case in which the long-term administration of glucocorticoid for rheumatoid arthritis might have concealed Cushing's syndrome, and conversely the increased intrinsic adrenal steroid hormone might have suppressed the activity of the rheumatoid arthritis.

Malignant tumors of the pituitary gland may mimic pituitary adenomas both in clinical presentation and in imaging, and often present with neurologic findings including visual field loss and extraocular movement palsies. We describe a 58-year-old woman without known malignancy who presented with extraocular movement weakness, loss of facial sensation, and a sellar plasmacytoma; a 49-year-old woman with oculomotor palsy, no known malignancy, and rapidly failing vision who had metastatic lung carcinoma; and a 70-year-old woman with metastatic breast carcinoma who presented with rapidly failing vision and a metastasis to the anterior lobe of the pituitary. These cases illustrate several important features of malignancy in the pituitary fossa: that it can mimic a "nonfunctioning" pituitary adenoma in clinical presentation and imaging; that rapidly progressive visual loss, extraocular movement palsies, or facial sensory loss may help to distinguish it from a benign adenoma; and that when the pathologist evaluates an alleged "nonsecretory" or "nonfunctional" adenoma, metastases should be included in the differential diagnosis.

The case history of a 65 year old female patient has been reported here by the authors. The patient was admitted to the Intensive Therapy Unit owing to her repeated heart pain. Later she was transferred to the Department of Medicine to establish the exact diagnosis. Prepyloric ulcer and hypertension were occurred in her history. The symptoms of her preceding as well as her recent illness were: pain in epigastric field, nausea, adynamia, weakness, polyuria, significant loss of weight, somnolence and the shortened Q--T time in electrocardiogram related to hypercalcemia syndrome. The calcium value in blood proved to be at critically high level from time to time. The possibility of the secondary hypercalcemic state was excluded by sonographic examination and the elevated level of parathormone in blood established the diagnosis of the hyperparathyroidism. The surgical resection of parathyroidic adenoma yielded a complete recovery of the patient. The authors call the attention to the significance of the clinical signs in the diagnosis of the disease.

A 55-year-old woman with bilateral multiple adenomas showed hypertension, muscle weakness, hypokalemia, moon-like face and truncal obesity. Increased serum and urinary levels of aldosterone were observed. Serum cortisol level did not show a normal circadian rhythm. Microscopic examination of the resected tumors showed two types of adenoma cells; one (golden yellow tumor) was a large clear cell with foamy cytoplasm which possibly secreted aldosterone and the other (dark brown tumor) was an acidophilic cell with lipofuscin which might have produced cortisol. This is a very rare case of primary aldosteronism with Cushing's syndrome due to multiple bilateral adrenal adenomas.
