A case is presented of a 60-year-old woman with fatigue, dyspnea, and chest pain. A chest x-ray film revealed an abnormal cardiac silhouette. Echocardiography revealed a large, echo-free area with well-demarcated, discrete borders adjacent to the right heart border. This structure decreased in size with inspiration and did not show pulsatile cardiac motion. Cardiac catheterization confirmed the extracardiac nature of the lesion and also showed a "constrictive" pattern with equalization of diastolic pressures. Surgical exploration revealed a large cystic thymoma. With removal of the tumor, intracardiac pressures returned to normal.

Twenty-two of 39 rabbits inoculated with Herpesvirus saimiri developed malignant lymphoma and either died or were killed between 17 and 165 days after inoculation. No clinical signs were present in animals developing the disease before 46 days, but all other rabbits had a severe conjunctivitis, nasal discharge, and dyspnea resulting from a lymphocytic invasion of the ocular and nasal tissues. Four rabbits developed terminal leukemia. Pathologically, the disease resembled H. saimiri malignant lymphoma in nonhuman primates; there was extensive diffuse infiltration of most organs and tissues with either a lymphocytic or lymphoblastic infiltrate. Tumor nodules or masses seen in some forms of malignant lymphoma were not present. In contrast to nonhuman primates, all affected rabbits showed invasion of the skin of the nose and eyelids, conjunctiva, iris, ciliary body, and choroid. In 3 rabbits there was slight infiltration into the brain, not noted in nonhuman primates. The susceptibility of rabbits extended the host range of H. saimiri beyond the order Primates.

The case of a 36-year-old women found to have a hepatic tumor is reported. The patient complained a malaise, weakness, dyspnea, and ankle edema and had been aware of a slowly growing abdominal swelling for 3 years. She had been taking Gynovlar 21 (3 mg norethinsterone acetate with 50 mcg ethinyl estradiol) for 6 years. Laparotomy revealed a solid, vascularized tumor arising from the left lobe of the liver and from part of the right lobe. A 2800 gm mass was excised along with a 40 gm mass from the celiac axis that involved lymphatic tissue. This is the 1st case report of a hepatic malignancy associated with an oral contraceptive that showed histological evidence of secondary spread.

Ventilation/perfusion scans were obtained in 45 patients with unresectable carcinoma of the bronchus. Of these 45 patients, 35 were reinvestigated shortly after radiotherapy and 17 of them had additional later follow-up studies. Both ventilation and perfusion were always abnormal in the lung affected by the tumor; perfusion was usually more impaired than ventilation. These abnormalities were difficult to detect or to evaluate from the standard chest radiograph. After radiotherapy, ventilation improved in 83% and perfusion in 86% of the patients. This improvement was associated with amelioration of breathlessness, which improved in 74% of the patients. Slow but progressive deterioration of regional ventilation and perfusion were subsequently observed. This was often associated with the development of radiation fibrosis. Spirometric measurements (VC, FEV1) were moderately imparied at the initial assessment (83% and 66% of predicted, respectively), probably due to coexisting chronic airway obstruction, and did not show significant changes after radiotherapy or during the follow-up. Radionuclide studies of regional perfusion and ventilation proved more sensitive and more specific than tests of overall lung function for the functional assessment and follow-up of patients with unresectable carcinoma of the bronchus.

Three cases of carcinoid tumor arising in the trachea are reported and contrasted with carcinoids arising in bronchi and carcinoids in general. Only eleven other documented examples of tracheal carcinoids are found in the English literature. The true prevalence of carcinoids primary in the trachea cannot be accurately determined from the literature because of imprecise nomenclature or because of the failure to distinguish this tumor from carcinoids primary in the bronchus. Presenting symptoms are hemoptysis, dyspnea and wheezing, often persisting for many years before the correct diagnosis is made. The treatment of choice is surgical resection of the involved segment of trachea and primary reconstruction. The prognosis is generally good. The tumor metastasized in one of our three cases and in none of the eleven cases in the English literature.

Ten patients developed pulmonary fibrosis after bischloroethylnitrosourea (BCNU) therapy for malignancy. This was lethal in seven patients, four of whom had no evidence of tumor at autopsy. Presenting symptoms were either the insidious onset of cough and dyspnea or the sudden onset of respiratory failure. Physical findings were unremarkable. Chest roentgenogram usually showed interstitial infiltrates. Pulmonary function studies showed resting hypoxia with diffusion and restrictive defects. This complication of therapy does not appear to be dose related and may be made more likely by the concomitant administration of cyclophosphamide. Prednisone therapy did not benefit most patients. The literature and the implications of the use of BCNU alone or in combination are reviewed.

Twenty-one cases of carcinomatous lymphangitis of the lung are reported. In diagnosing them clinical, roentgenologic, and histopathologic criteria were used and the clinical, roentgenologic and evolutive findins were considered in order to emphasize the origin of the primitive neoplasm. From this point of view the principal ones turned out to be carcinomas of the breast, stomach, and lung. The absence of carcinoma of the thyroid gland as a source of pulmonary lymphangitis carcinomatosa must be pointed out. The higher incidence of this condition in older people and the clear predominance in the female sex are stressed. From a clinical standpoint the most important data were the existence of cough and dyspnea, which are often associated with the commom presence of enlarged left supraclavicular or axillary lymph nodes. There was a predominant pure interstitial pattern (the most common feature was the presence of Kerley's A or B lines), sometimes coexisting with alveolar impairment and very often with accompanying pleural effusion. The mean survival rate was 2 months, with a maximum of 7 months and a minimum of 3 days. The results of the present series were compared with those of the literature and the most significant and constant fact in both instances was that two thirds of the cases of pulmonary lymphangitis carcinomatosa had their origin in neoplasms of the breast, stomach, and lung.

23 deaths of patients with severe asthmatic dyspnea were analyzed. There was no correlation between clinical presentation and cause of death certified by post-mortem examination. The cause of death was found outside the airways in 14 patients. Of diagnostic-therapeutic implications are the relative frequency of spontaneous pneumothorax (5) and pulmonary embolism (3). Six times another cause of death was discovered (like tumor invasion, arterial thrombosis, hemorrhagic pancreatitis, myocardial infarction). Acute asthmatic death was prone to happen in the middle-aged asthmatic with less than two years of bronchial asthma. Here like in 5 patients with chronic obstructive airways disease lack of awareness of the seriousness of the patients' state, sometimes cessation of cortisone long-term therapy, seldom abuse of bronchodilator-aerosols seems to be important for the lethal outcome.

A very rare case of a myxosarcoma with metastases to the brain is reported. A 33-year-old female was admitted to our hospital because of lassitude, fever, slight left hemiparesis, headache and other signs of intracranial hypertension and cardiac symptoms such as dyspnea and palpitation. She had the cardiac symptoms once 14 years before, which reappeared and rapidly aggravated two months before the admission. Cerebral angiography revealed a mass in the right temporal lobe and physical and laboratory examinations revealed mitral value failure and hyperthyroidism. On the next day, March 19, 1976, a grossly cystic 60 gm tumor was totally removed which was largely imbedded in the subcortex of the right temporal lobe. The symptoms except for the cardiac symptoms and disseminated intravascular coagulopathy rapidly improved, but headache and left hemiparesis returned 13 days postoperatively. She died suddenly 18 days after the operation due to acute cardiac failure. Autopsy revealed two separate hard and solid tumors both attached to the mitral valve and occupied the whole left atrium and another metastasis to the frontal lobe which had not been diagnosed before the death. Microscopic examinations including electronmicroscopic study established the diagnosis of myxosarcoma in all the four tumors.

A 46-year-old man had a granuloma in the neck that was caused by extravasation of thorium dioxide (Thorotrast) by an angiographic procedure performed about 30 years previously. His chief complaints were dysphagia and dyspnea with mild hoarseness. Parital resection of the tumor was performed, but his symptoms were not ameliorated. The immediate postoperative course was unfavorable. The patient died four months after the operation from massive hemorrhages from the right common carotid artery.
