Cervical intraepithelial neoplasia in human consist of dysplasia of various developmental stages and squamous cell carcinoma in situ of various types. These lesions can be diagnosed cytologically on cervico-vaginal smears, although the diagnostic reproducibility is limited. To obtain the objects morphologic distinction between normal squamous epithelial cell in different maturation, different stages of dysplastic cells and varieties of in situ carcinoma cells, Kontron IBAS-1 imaging analyzer was applied for the measurement of nuclear and cytoplasmic areas of each categorised cells. The followings are results obtained: 1) Nuclear and cytoplasmic areas of superfical (36.9 micrometer2, 2319.9 micrometer2) intermedicate (45.7 micrometer2, 2989.7 micrometer2) and parabasal cells (50.8 micrometer2, 432.7 micrometer2) of normal squamous epithelium origin are mostly distinctive between cell types. However, cytoplasmic areas of both superficial and intermediate cells and nuclear areas of both intermediate and parabasal cells are not significantly different. 2) Normal squamous cells and various dysplastic cells show obvious difference in their nuclear and cytoplasmic areas, while difference between cytoplasmic areas of both parabasal (432.7 micrometer2) and severe dysplastic cells (409.7 micrometer2) are not statistically significant. 3) No statistical difference is observed in between nuclear areas of both moderate dysplastic (112.3 micrometer2) and severe dysplastic cell (117.6 micrometer2). 4) Varieties of carcinoma in situ cells and severe dysplastic cells are in difference in their nuclear and cytoplastic areas, whereas nuclear areas from both in situ carcinoma cells (95.3 micrometer2) of large cell type and severe dysplasia (117.6 micrometer2) are not distinctive. The results lead the author to consider that the morphometric analysis for various parameters of cell constituents are of value in making objective distinction between cells from cervical intraepithelial neoplasia in human.
