The Exfoliative Cytology of Diffuse Malignant Mesothelioma.

ALTHOUGH excellent accounts have been published in recent years of the gross and histological pathology of neoplasms believed to be diffuse malignant mesotheliomas, there remains a scarcity of adequate descriptions of their exfoliative cytology. One purpose of this paper is to help correct this deficiency. Another is to present further evidence that diffuse malignant mesothelioma really exists,...

Exfoliative cytology of diffuse mesothelioma.

The exfoliative cytology of 14 diffuse mesothelioma (11 pleural and three peritoneal) is described. Malignant cells were identified in 10 patients; in eight malignant cells still retaining the characteristics of mesothelial cells were found. It is suggested that only if malignant cells of this type are recognized should the probable diagnosis of diffuse mesothelioma be made.

Diffuse meningeal thickening associated with pleural mesothelioma.

A case of pleural mesothelioma with diffuse spinal meningeal thickening as shown by magnetic resonance imaging is reported.

Electron microscopy in the cytological examination of metastatic pleural effusions.

In a previous publication the ultrastructure of pleural effusions in cases of pleural mesothelioma was reported. The same method has now been applied to a study of effusions produced by pleural metastases. The findings are considered sufficiently conclusive to justify the use of electron microscopic cytology in determining the nature and sometimes the origin of such effusions.
