[Cytodiagnosis of pleural exudates with electron microscopy. II. Tumorous exudates of glandular origin].
Detailed examination of 26 pleural exudations by transmissive and scanning electron microscopy gave new cytodiagnostical possibilities. In addition to confirming the light-microscopical criteria of malignancy transmissive electron microscopy characterized the cells of adenocarcinoma by microvilli with common structure, various length, irregular orientation and crossing over or branching. They tend to be a bit widened at their base or top and to cover all the surface of cells. Microvilli in the neighbouring parts of cells are less numerous, irregularly oriented, shortened and interdigitating. Not even here is the surface of carcinoma cells quite smoth in contrast to neighbouring mesotelial cells. Scanning electron-microscopical examination being neither technologically sophisticated nor time consuming enables a scope on cellular surfaces uniformly covered by countless microvilli densely distributed.
