[Morphometric characteristics of squamous cell lung carcinoma (light and electron microscopy studies)]

Combined study of pulmonary squamous cell carcinoma of different degree of cataplasia was carried out at the tissue, cellular, and subcellular levels using a quantitative method of evaluation of different morphological criteria. Most informative criteria reflecting the degree of tumor cataplasia were distinguished: at the histological level--the degree of keratinization and intensity of stratification; at the cytological level--nucleus-cytoplasm ratio; at the electron microscopic level--volume of keratohyalin fraction and the degree of functional activity of polyribosomal apparatus. A definite correlation between these parameters with a high level of significance was established.
