A man of 38 years of age was found to have a type I endocrine polyadenomatosis in 1969. He was operated upon for removal of tumor of the islets of Langerhans with lymph gland
metastases
, and the head of the pancreas was removed. This was followed at a later date by ablation of two parathyroid adenomas. A clinically silent
adenoma
of the left adrenal was not removed and a silent and enclosed pituitary tumore was discovered. There were no clinical or hormonal signs of progression of the pancreatic tumor ten years later, but hypertension and behavioural disorders had developed. Catecholamine levels were normal. Selective blood aldosterone levels were just within significant values. A massive increase in prolactin secretion (more than 100 times the normal) was noted. This could be reduced by bromocriptine, and the possible role of prolactin in the behavioural disorders present is discussed.

Polyamine levels (putrescine, spermidine, spermine) were determined in 24-hour urine samples by a high voltage electrophoresis technique. Normal values were established in 42 normal volunteers. Thirty-eight of 56 patients with
metastatic cancer
had two or more levels elevated. Approximately two-thirds of patients with metastatic adenocarcinoma, metastatic squamous cell cancer or
metastatic disease
to the liver, lings, or bones had elevated levels. All 6 patients with localized malignant tumors had elevated urinary polyamine levels. Elevations were also seen in patients with benign prostatic hypertrophy and bronchial
adenoma
.

A solid
adenoma
of the pigmented ciliary epithelium was removed by 9.0 X 6.0 mm "block-excision" (postoperative visual acuity 1.0). The black lesion with a velvety surface consists of very large cells packed with melanin granules of abnormal and variable density, structure and size. Striking intracellular vacuoles contain acid mucopolysaccharides, particularly sialomucins. The literature on tumors of the pigmented ciliary epithelium is reviewed. Criteria for the separation of adenomas for adeno- "carcinomas" (8 cases, all without
metastases
) from reactive hyperplasia (6 cases) are proposed. The histologic, histochemical and electronmicroscopic findings of our tumor show striking similarities to those of an
adenoma
of the retinal pigment epithelium.

Hematogenous
metastases
of benign pleomorphic adenomas are exceptionally rare. In three secure reports of the world literature
metastases
occurred in lung, liver or bone after operation of a benign pleomorphic
adenoma
with the greatest interval of twenty-two years between operation and
metastases
. This will be interpreted as implantation-
metastases
. All other observations represented secondary carcinomas in pre-existing pleomorphic adenomas. The morphological criterias of an accurate classification are explained. A number of reports of the literature about
metastases
of benign pleomorphic adenomas deals with misinterpretations of secondary adenomas in pre-existing pleomorphic adenomas.

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.

An autopsy case of radiation-induced intracranial malignant fibrous histiocytoma (fibroxanthosarcoma) is reported. The tumor developed in the region of the sella turcica 11 years after high dose radiotherapy of a chromophobe
adenoma
of the pituitary. The tumor had infiltrated the base of the brain as well as the base of the skull.
Metastases
were not found. The tumor was composed of an admixture of bizarre fibroblasts, histiocytes and giant cells, xanthoma cells and siderophages, with a storiform fibrous stroma. This appears to be the first documented instance of a malignant fibrous histiocytoma occurring intracranially after local x-irradiation.

Continued uncertainty about the prognosis for patients with bronchial adenomata led to a review of the experience of this condition in the Brompton Hospital. Of 72 patients seen between January 1955 and December 1972, 39 were women and 33 men, mean age 45 years, range 9-73 years. The commonest presenting symptoms were haemoptysis, cough, sputum, and repeated chest infections. Positive bronchoscopic biopsy occurred in 35 of 43 cases; five of these were originally reported as carcinomata, of oat-cell type in four. Plain chest film abnormality occurred in 69 patients. Seventy-three operative procedures comprised two endoscopic removals, two wedge resections, six bronchotomies, five pneumonectomies, and 58 lobectomies (seven with sleeve resection). Recurrence in three of six bronchotomies--two with adenoid cystic carcinomata (cylindromata)--necessitated further surgery. Lobectomy and lymph node dissection is usually the operation of choice. Histology confirmed 67 carcinoids (eight with atypical histology or lymph node
metastases
), two adenoid cystic carcinomata, one muco-epidermoid, and two mucous gland adenomata. Prolonged follow-up is especially indicated in patients with adenoid cyst carcinoma and in those with atypical or metastatic carcinoid histology. Although such pathology is not incompatible with long survival, of 10 patients in these categories, all five late deaths were probably related to the tumour. However, of 57 patients considered to have had typical carcinoid histology and adequate removal of the tumour, there has to date been no tumour-related death, but one patient developed radiosensitive atypical carcinoid tracheal tumours nine years later. The actuarially assessed survival of 71 patients undergoing surgery for bronchial adenomata was 75% at 15 years. Specific tumour types should replace the term bronchial
adenoma
.

The effect of chronic administration of 2,2'-dihydroxy-di-n-propylnitrosamine (DHPN) was studied in randombred guinea pigs. DHPN, dissolved in olive oil, was injected sc into 40 animals at a dose of 250 mg/kg body weight/week for 30 weeks, and the animals were observed until their death or termination of the experiment at the end of 40 weeks. Of the 32 guinea pigs that survived more than 20 weeks of DHPN treatment, 23 developed angiosarcoma of the liver between 22 and 40 weeks.
Metastases
to lungs, spleen, and peripancreatic lymph nodes were observed in 8 animals. Other tumors included hepatocellular carcinoma (1 animal), cholangiocarcinoma (1 animal), chronic myeloid leukemia (1 animal), acinar cell
adenoma
of pancreas (1 animal), and acinar cell carcinoma of pancreas (1 animal). In addition, megalocytic change of hepatic cells with intranuclear inclusions, pelliosis hepatis, and cholangiomatous lesions were also encountered frequently in the livers.

Twenty-four patients with bronchial
adenoma
seen over a 20-year period are reviewed. Follow-up data was available in all patients. They included 19 with carcinoid, 2 with adenoid-cystic carcinoma, and 3 with muco-epidermoid carcinoma. Recurrent pulmonary infection, cough and hemoptysis were the most common clinical manifestations. Surgical resection was performed in all but one patient, who was treated by irradiation; bronchoplastic and conservative resectional procedures were used in 5 patients with carcinoid
adenoma
. Carcinoid tumors are considered to be very slowly-growing malignant neoplasms that sometimes give rise to
metastases
to regional lymph nodes. Such
metastases
were present in only one patient. All patients are alive and well. Adenoid-cystic carcinoma is a more aggressive tumor with a tendency to recur. Much of the difficulty in its treatment is due to its close proximity to the bifurcation of the trachea. One patient was operated upon three times for local recurrences and ultimately died from respiratory failure after the third operation. The other patient received radiation therapy with cobalt and is well, without recurrence, 3 years after the treatment. The 3 muco-epidermoid carcinomas were histologically similar to such tumors of salivary glands but behaved clinically like highly malignant tumors, no patients surviving 8 months after resection. The term bronchial
adenoma
is a misnomer. The neoplasms grouped under this heading should be called carcinoid
adenoma
, adenoid-cystic carcinoma, and muco-epidermoid carcinoma and considered as separate entities, since the ultimate course and prognosis is definitely different.

We report on four patients, aged seven months to seven years, with virilizing adrenal cortical tumors. Diagnosis was made by clinical and laboratory data. Tumor localisation was achieved preoperatively in three patients. In two patients both androgen and glucocorticoid excretion were elevated. In three patients histological examination showed a carcinoma, in one patient an
adenoma
was suggested. There were no
metastases
. In two patients surgical removal was followed by cytostatic therapy, in one of them additional irradiation treatment was carried out. This child died 10 1/2 years later from a metastasizing renal cell carcinoma which originated from the kidney being situated in the irradiated area.
