[Comparing electron microscopical investigation of cells from mesotheliomas (author's transl)]. 1977

H Jaugitz

The difficulties of diagnosing cells originating in mesotheliomas by light microscopic methods are well known. Therefore we tried to find some additional criterions for the cytologic diagnosis using electron microscopy. Only the microvilli seemed to be a distinct criterion as seen by electron microscopy. By this we were able to differentiate mesothelioma cells from macrophages which exhibited large appendices of their cell borders.

UI	MeSH Term	Description	Entries
D008654	Mesothelioma	A tumor derived from mesothelial tissue (peritoneum, pleura, pericardium). It appears as broad sheets of cells, with some regions containing spindle-shaped, sarcoma-like cells and other regions showing adenomatous patterns. Pleural mesotheliomas have been linked to exposure to asbestos. (Dorland, 27th ed)	Mesotheliomas
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D010996	Pleural Effusion	Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself.	Effusion, Pleural,Effusions, Pleural,Pleural Effusions
D010997	Pleural Neoplasms	Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.
