Morphometry in evaluating large cell malignant lymphomas in lymph node biopsies.

The values of some morphometric cell parameters were analysed in 12 cases of large cell non-Hodgkin's lymphoma (centroblastic and immunoblastic lymphoma and histiocytic sarcomas) in order to test the utility of the morphometric method as an additional element to the histologic diagnosis and to its further accuracy. The nuclear and nucleolar area, the number of nucleoli per nuclear cross section and the nucleus to nucleolus ratio were investigated. The morphometric data were obtained on histograms using the Giemsa stained sections. Mean values and standard deviations were calculated and statistically analyzed. Statistical evaluation of data showed significant differences in the three groups. Our results proved the usefulness of the morphometric method as a helpful technique of differentiating the large cell malignant lymphomas.
