Stereological analysis of non-Hodgkins lymphomas.
A detailed stereological analysis was carried out on 30 lymph nodes at 2 ultrastructural levels. They were classified as follows: 10 were reactive lymph nodes, 10 were of low-grade non-Hodgkins lymphomas and 10 were of high-grade non-Hodgkins lymphomas. The mean and median values and interquartile ranges of nuclear profile diameter, nuclear volume, volume of cytoplasm, cell volume and absolute number of ribosomes were recorded for each case. The model proved very efficient in establishing several significant differences between the highgrade and lowgrade lymphomas and between the highgrade lymphomas and reactive lymph nodes but did not discriminate between lowgrade lymphomas and reactive nodes, nor did it distinguish neoplastic cells from reactive cells in the neoplastic group. The significance of these findings is discussed.
