Use of morphometry in cytological preparations for diagnosing follicular non-Hodgkin's lymphomas.

Morphometric techniques were applied to cytocentrifuge smears from 27 patients with histologically confirmed follicular non-Hodgkin's lymphoma to determine the usefulness of this method in diagnosis. Analysis of quantitative data confirmed that most subtypes were classified correctly on the basis of the proportion of large cells, small cleaved, and large non-cleaved cells, and nuclear, nucleolar, and cytoplasmic features. Morphometry is a more objective and reproducible technique than manual cell counting methods, and the use of cytocentrifuge smears has several advantages compared with conventional histological sectioning. Data derived with the aid of morphometry may be of value in follow up clinicopathological studies.
