A series of 46 malignant schwannomas occurring in soft parts of patients having von Recklinghausen's neurofibromatosis was analyzed. The diagnosis of malignant schwannoma was based upon the occurrence of malignant spindled cells closely resembling Schwann cells in the
neoplasm
and the close association or origin of the malignant schwannoma in a neurofibroma (27 tumors), or a large peripheral nerve (31 tumors). Additional histologic features useful in making the diagnosis of malignant schwannoma included the arrangement of the spindled
tumor
cells in a whorled pattern about thin-walled, gaping blood vessels, perivascular cellular proliferation and the presence of prominent myxoid stroma containing abundant hyaluronidase-sensitive acid mucopolysaccharides. Nuclear palisading was present in only one case. Eight tumors containing both neoplastic Schwann cells and rhabdomyoblasts and five containing both neoplastic Schwann cells and rhabdomyoblasts (malignant "Triton" tumors) and five containing foci of malignant cartilage cells were included in the series. The neoplasms occurred principally in adults (median age, 34 years) and were most common in the lower extremity (18 cases) and retroperitoneum (11 cases). A mass with or without
pain
was the most common presenting symptom (28 cases). The median size of excised tumors was 11 cm. The malignant schwannomas were highly malignant neoplasms, causing the death of 39 patients within five years and two patients within 6--10 years after diagnosis. Only four patients were alive and free of
tumor
5--15 years after diagnosis.

The objective of this study was to learn the course of child's adaptation process to school and family environment following the
neoplastic disease
. The study also aimed select the environment and personality factors influencing adaptation effect. The study pertains to the child's personality and how it works at home and at school. It also tries to get to know the child's environment. 65 children of different social environment were studied. Motor functions of these children were limited as the result of tumour disease. Special scale of adaptation was prepared when the research was over. By means of this sale two groups of children were distinguished: those who were well adapted to the environment and those who were not. Statistical analysis was used to compare the groups on account of the following factors: health factors including: a kind of tumour, duration of the disease, prevalence of
pain
, manipulation and locomotive abilities, visibility of handicap; sociological factors including: age and sex of studied persons, the place of residence and education of parent's, living standard of the family, a degree of family participation in cultural life of the society, mother's attitude towards the insane child. These factors allow to formulate the following dependences: The more a level of the child's locomotive functions, following
neoplastic disease
approaches to the standard, the more favourable course takes the process of child's adaptation to the family and peers. If a
neoplastic disease
leaves permanent and always visible handicap then child's adaptation effect to the environment is not favourable. An active participation of the family in socially life is beneficial for regular adaptation of a child. Personality development as the result of participation in cultural life allows socially accepted defence mechanism to work in stress situations connected with the disease. Parent's rational attitude towards an insane child correlates with a beneficial child's adaptation to an environment. Other factors did not differentiate the two groups statistically. During clinicalontgenetic analysis concerning particular studied cases, 3 models of nonfunctional adaptation were distinguished: maladjustment of aggressive type prevailing among the children with permanent physical handicap coming of families characteristic for socially nonaccepted standard of behaviour; maladjustment of neurotic type prevailing among the children coming of compliant families whose adult members manifest neurotic vegetative reactions in difficult situations.(ABSTRACT TRUNCATED AT 400 WORDS)

This case report concerns a 30-year-old white woman who had taken C-Quens for a period of a 6 years after 2 normal pregnancies. A third normal pregnancy had followed. At 5 weeks postpartum sharp
pain
in the upper abdomen occurred with weakness and fainting. Blood pressure was 60 mg of Hg, systolic hemoglobin 9.4 gm per 100 ml, and hematocrit 28.5%. Abdominal aspiration revealed hematoperitoneum. At an emergency operation a ruptured
tumor
of the left lobe of the liver was found; it was removed with most of the left lobe. Histologically the
tumor
was diagnosed as a hepatic adenoma, a benign liver cell
tumor
. Previously this has been a rare
tumor
type. Recently 12 other cases have been reported among young women who have been using oral contraceptives for long periods. This suggests an etiological relationship. Of the 12 patients reported by others, 6 have died, 5 after emergency surgery. The author's patient recovered.

A female patient with Gardner's syndrome was treated with delta1-testololactone (200 mg daily) because of growth of a large desmoid tumor in the pelvis and lower abdomen and a
tumor
in a scar from a previous laparotomy. There was also
pain
and swelling of the left leg. An immediate effect of the drug therapy was complete relief of
pain
followed shortly thereafter by disappearance of the edema of the leg. After two months, the numerous sebaceous cysts were less prominent. The gross measurements of the diameter of the pelvic and lower abdominal
tumor
clearly demonstrated
tumor
shrinkage following therapy. Small polyps scattered over the rectal mucosa and numerous osteomata were not demonstrably affected. After one year of treatment with delta1-testololactone, a laparotomy for partial small bowel obstruction was necessary. Obstruction was caused by the involvement of small bowel mesentery and the bowel itself in a contracted residuum of dense fibrous tissue. Substitution of theophylline and chlorothiazide for the testololactone in Januray 1974 was followed by further diminution of the measurable abdominal and pelvic desmoids. All of these compounds synergize the action of 3',5'-adenosine monophosphate and at least the latter two may function by inhibiting the action of 3',5'-adenosine monophosphate diesterase.

In 26 of 227 patients with carcinoma metastatic to the eye or orbit, metastasis to the anterior uveal tract was the predominating feature. There was a definite propensity for the
tumor
to involve the horizontal meridian of the iris or ciliary body, rather than the upper or lower portions. The site of the primary tumor in the 26 patients was as follows: lung 14; breast, 9; kidney, 2; and rectum, 1. Ocular symptoms and signs produced by the metastatic tumors at onset or during the course of the disease included decreased vision (80%), a visible mass (72%), redness of the eye (56%),
pain
(56%), glaucoma (56%), iridocylitis (44%), and hyphema (24%). The median survival of the 26 patients with metastasis to the anterior segment of the eye was only 5.4 months from the time of ocular surgery. This is poorer than the median survival (7.2 months) of the patients with metastasis confined to the posterior segment, and much worse than the median survival (15.6 months) of the 28 patients with orbital involvement.

Of 112 000 patients undergoing surgery between 1952 and 1973, 67 had a primary tumor of the small intestine. 22 patients had a benign tumor, 8 a carcinoid, 21 carcinoma and 15 sarcoma. Benign tumors were more frequent in the duodenum and ileum, carcinoids in the terminal ileum and carcinomas in the duodenum and jejunum. Sarcomas were found equally in all parts of the small intestine. The most common symptom for all types of the
tumor
was variable
pain
in the abdomen. Loss of weight occurred only in patients with carcinomas and sarcomas; heavy intestinal blood loss was most common in patients with benign tumors. Benign tumors often show invagination, while sarcomas cause occlusive ileus or perforation. All duodenal tumors show heavy intestinal bleeding but hematemesis is rare. Emergency surgery was necessary in 42% of patients with benign tumors or sarcoma and in 30% of patients with carcinoma. Five-year survival in patients with benign tumors is excellent (100%). Compared to this, five-year survival in patients with carcinoma, sarcoma or carcinoids is only 15%.

During a 23 year period at Memorial Hospital, the diagnosis of liver cell carcinoma was made in 42 patients who were 11 to 40 years old. Ninety per cent were Caucasian, mostly born in the United states. No occupational hazard was detected. Serum hepatitis antigen was demonstrated in only one patient. Alpha fetoprotein was found in the serum of 55 per cent of nine patients tested. Eight-three per cent were Rh positive, 43 per cent were ABO groups, A or O, respectively. Twenty-three per cent of 13 patients with sufficient material for study had an associated cirrhosis. Of these, active hepatitis with cirrhosis was present in one patient; postnecrotic cirrhosis was present in another. Approximately 7 per cent had a history of previous liver disease. One patient had infectious mononucleosis, and nearly 13 per cent gave a family history of cancer. Weight loss or
pain
in the right upper abdominal quadrant was present in 65 per cent, and hepatomegaly was found in 88 per cent. Only one patient presented with hemoperitoneum simulating an acute condition within abdomen. The liver profile examinations characteristically revealed an elevation in serum alkaline phosphatase, 5 nucleotidase, and Bromsulphalein retention with normal bilirubin level. The most common finding, upon roentgenographic examination, was an elevated right hemidiaphragm. Selective celiac and superior mesenteric angiography and 99mTc sulfur colloid liver scans were both done in 13 patients. There was a 75 per cent accuracy rate in localization of the
tumor
. At laparotomy, the
tumor
was found to be confined to one lobe in seven patients and involved both lobes in ten. Twenty-seven patients were thought to have multicentric tumors and 15 unicentric lesions. Only ten were found to be candidates for hepatic lobectomy. Five and ten years survival rates were 20 per cent; the operative mortality rate was 40 per cent. Twenty per cent died within a year, ten per cent, one patient, is alive with disease at 28 months and another is free of disease at 31-months. Paraneoplastic syndromes were erythrocytosis in two patients, terminal stage of hypoglycemia in one patient, and hypocholesterolemia with associated excess beta globulin in one patient.

Fifty cases of oral minor salivary gland adenoid cystic carcinoma (ACC) are analyzed and reported. Oral ACC frequently masquerades as a benign
neoplasm
, and in the majority of cases there is no
pain
or ulceration. The most common location is in the palate; a plea is made for incisional biopsy of all oral lesions suspected of salivary gland origin. Survival rates show a progressive decrease with time, and there were no survivors beyond 20 years. In this study, there was a positive correlation between duration of the lesion before diagnosis and the salvage rate, but no correlation was found with the size of the presenting lesion.

The ability of L-dopa to arrest
pain
can be used to predict objective response of skeletal disease to endocrine ablation or additive therapy. In the present study, 43 patients with painful skeletal metastases were evaluated for the relief of
pain
by L-dopa, given 250 mg to 500 mg orally every 4 hours for 4 days. Sixteen of the 25 responders to L-dopa had objective response to either previous or later hormonal therapy while all the 18 non-responders did not benefit from endocrine ablation. The results of L-dopa responses also correlated well to the presence of absence of cytoplasmic ER in
tumor
. These results demonstrate that both tests (L-dopa and ER) are reliable indicators, one complimenting the other, in prognosticating response to endocrine therapy and should be used prior to hormone treatment. Alternative therapy should be considered for patients who are non-responders to the L-dopa test and/or whose tumors contain negligible ER. The long term therapeutic value of L-Dopa, however, is limited.

A case of Abrikossof
tumor
in a 33 year old patient presenting a progressive growth of a toe without associated
pain
or inflamation. There was an important hypertrophy of the affected toe with hyperkeratosis and pseudoelephantiasis. The histologic examination showed a massive infiltration of granular cells in the dermis. The exceptional localisation of the
tumor
in this case is emphasized.
