16 lung large cell carcinomas (13 of them were followed for a long time) were studied. It is established that these tumours are a heterogeneous group of neoplasms which may be undifferentiated or with squamous, glandular, oncocytic and endocrine differentiation. Ultrastructural classification is presented reflecting diagnostic and prognostic aspects of these tumours. Tumours with pneumocytes type II, oncocytic differentiation and many lipid inclusions have more favourable prognosis. Unfavourable prognosis is typical for large cell carcinoma formed of undifferentiated cells only or with differentiation in the direction of goblet cells.

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

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
