Sixty-four cases of dysplasia, high degree, of cervical epithelium were histologically classified into immature, premature and mature dysplasia according to their cytoplasmic maturation.
Cytologic samples of the same cases were also classified into metaplastic, nonkeratinizing and keratinizing dysplastic cell type by the description of Dr. S. F. Patten.
No keratinizing dysplastic cells were found in the immature dysplasia classified histologically.
Metaplastic dysplastic cells were scarcely included in the mature dysplasia.
The samples classed to the premature dysplasia had various cell types.
