Abstract

CEDENO B, Floribel  and  FINOL, Héctor J. Ultrastructural pathology of inflammatory infiltrate in epithelial dysplasia And oral spinocellular carcinoma. Acta odontol. venez [online]. 2008, vol.46, n.4, pp.478-480. ISSN 0001-6365.

It has been observed that many neoplasms are developed in association with inflammation, infection and chronic irritation, which is the case of oral Spinocellular Carcinoma and previous states of Epithelial Dysplasias. The purpose of the present work was to study ultrastructurally : inflammatory infiltrate in epithelial lesions related to Dysplasia and oral Spinocellular Carcinomas by routine techniques for transmission electron microscopy. Observed presence of inflammatory infiltrate and the frequent interactions between cells of infiltrate and with neoplastic cells suggests its active participation in the development and progression of oral Spinocellular Carcinoma given the etiopathogenia of these lesions and the intimate relation among microenvironment generated by chronic inflammation and tumor epithelial cells.

Keywords : inflammatory infiltrate; Epithelial Dysplasia; Spinocellular Carcinoma.
