Outline of Final Research Achievements |
To evaluate the possibility of tumor stroma in lamina propriae of carcinoma in situ (CIS), the distribution of lymphatics and blood vessels, oral submucous fibrosis, the expression of extracellular matrix were investigated in CIS, normal epithelium, epithelial dysplasia and squamous cell carcinoma (SCC). Lymphatics in CIS were characterized by their closed lumen, irregular shapes. The distribution mode of closed and irregular shaped lymphatics in the peripheral invasive front of SCC resembled those of CIS. In CIS, the elastic fiber were irregularly formed and aggregated, and muscle fiber were denatured sporadically with slightly immunopositive stain due to the submucous fibrosis.
