Cytologic examinations of pleural exudate and cyto-histological examination of biopsies taken from the pleura give useful contributions in the differential diagnosis of primary chronic nonspecific pleurisy. In the early stage of disease the cellular findings are characteristic and enable easy differentiation of mesothelioma. Later on in primary chronic nonspecific pleurisy alterations of mesothelial cells can be seen which mimic tumorous cells and may be erroneously taken for mesothelioma cells. Quantity and quality of these alterations of nucleus and cytoplasma of mesothelial cells in primary chronic nonspecific pleurisy can be distinguished from tumor cells of mesothelioma by critical evaluation in the majority of cases.

We report a case of mesothelioma of the atrioventricular node with congenital complete heart block and sudden death in a 15-year-old girl. This benign tumor probably represents a hamartoma derived from mesothelium with a constant anatomic location and uniform association with heart block. The clinical course of such patients, however, has been variable. The tumor has been associated with sudden, unexpected death in infancy or adolescence, but has more often been discovered as an incidental finding at autopsy in a middle-aged or elderly patient.

A case report of a patient who developed peritoneal mesothelioma 7 years after internal and external irradiation for carcinoma of the cervix is reported. No previous reports of induction of this tumor by irradiation have been found. The subject of radiation-induced tumors and peritoneal mesothelioma is briefly discussed.

One hundred six patients with malignant pleural effusion were treated by pleurectomy; 83 of these were available for a 2-year followup. Sixteen of 83 patients were alive 2 years following the pleurectomy, with a survival range of 2-6 years. The most common neoplasms associated with the development of effusion were carcinoma of the lung in 41 cases, carcinoma of the breast in 33 cases, and mesothelioma in 14. Indications for pleurectomy were: A) failure to control the effusion by tube drainage and instillation of chemical or radioactive agents; B) presence of a trapped lung; and C) presence of malignant effusion at the time of thoracotomy for resection of an intrathoracic tumor.

A case of hypoglycemic coma and benign pleural mesothelioma is described. Serum insulin levels, as measured by insulin radioimmunoassay, were appropriately suppressed and consistent with hypoglycemia. Assay of the tumor showed insulin to be undectable. The mechanisms for hypoglycemia probably included increased glucose consumption by the tumor and, more important, the inhibition of lipolysis and hepatic gluconegenesis caused by tumor release of L-tryptophan and its metabolites and/or possibly nonsuppressible insulin-like activity, soluble in acid-ethanol(NSILA-s).

A case of mesothelioma of the atrioventricular node is presented. The patient had complete heart block for many years before death. The origin of the tissue in this apparently congenital tumor is discussed with reference to the literature.

The prevalence of asbestos bodies was measured in lung sections in a necropsy series carried out at the London Hospital (1965-66) after exclusion of all known asbestos factory workers and cases of asbestosis and of mesothelioma. Associations were sought between the presence and number of asbestos bodies with the patients' sex, domiciliary address, occupation, industry, and diseases recorded at necropsy. Asbestos bodies were present in 42% of the 216 men in the series and in 30% of the 178 women. The number of bodies in the positive cases was small in comparison with the numbers seen typically in asbestosis; thus there were less than 6 asbestos bodies per 6-75 mm-3 lung tissue in 107 of the total 145 positive cases in contrast to 1 000 or more in asbestosis. In comparison with the overall series, an increased number of asbestos body positives was present in males with carcinoma of stomach and females with carcinoma of breast. In view of this finding lung sections were counted in further post-mortem examples of these carcinomas making a total of 50 males with carcinoma stomach and 82 females with carcinoma breast. Thirty-five positive cases were found in the carcinoma stomach group as against 22-7 expected and 38 in the carcinoma breast group against 26-35 expected. There was no excess of observed over expected asbestos body positives in 51 males with carcinoma of bronchus. There was an excess of asbestos body positives (60-9%) in heavy manual workers and in both heavy and light manual male workers in the shipping (61%), electrical and engineering (56%), and transport (54%) industries. The incidence in male clerical workers was 12-8%. The incidence of asbestos body positives according to home address was highest (53% in males, 45% in females) in patients living in the industrial and cockland area due east of the hospital. The incidence fell in the less industrial areas north-east of the hospital. Consideration of possible environmental sources of the inhaled asbestos suggests that in this survey occupation, industry, and comiciliary area all play a part. The comparatively minor intensity of asbestos pollution in our positive cases showed a positive association with carcinoma of stomach and breast, possibly playing a direct pathogenic role in carcinoma of stomach. No positive association was identified with any other neoplastic disease including carcinoma of bronchus.

Sudden death of a 21-year-old women. The cause of death was mesothelioma situated in the region of the interatrial septum that has been manifested since childhood as a complete heart block. Neither gravidity nor delivery led to the aggravation of her state of health. The cause of this heart lesion, which was the mentioned rare tumor, was discovered only during the autopsy.

The materials concerning 19 patients with pleural mesotheliomas are analysed. The patients were subdivided into three groups according to the clinico-roentgenological picture and course of the affection: 1) four patients in whom pleural mesothelioma proceeded without exudate accumulation; 2) seven patients in whom exudate accumulation in the pleural cavity was the main sign of the tumor; 3) 8 subjects in whom the tumor developed on the side of an artificial pneumothorax many years following its cessation. Among 19 patients only in 5 cases the tumor was suspected soon after their admission to the hospital. A needle biopsy of the pleura is felt to be the most effective method of diagnosis of pleural mesotheliomas, whereas in failure of the former -- pleuroscopy.

Histologic study of the conduction system of the heart of a 16-year-old girl who died suddenly demonstrated a benign mesothelioma of the AV node, with almost complete replacement of the structure by the tumor. Teh past history was unremarkable, except for few syncopal episodes at 9 and 11 years of age and during pregnancy. Immediately postpartum, she developed a 2:1 AV block and intermittent complete AV block. Six weeks later, during diagnostic work-up in the cardiac catheterization laboratory, she died suddenly. Electrophysiological studies during this work-up disclosed complete AV dissociation, with normal QRS complexes. The block was proximal to the His-bundle recording site, with a normal H-V interval. Occasional syncopal attacks in young adults should alert the physician to the possibility of this diagnosis and lead to pacemaker insertion.
