Avaliação das características microscópicas presentes nas hiperplasias inflamatórias

The inflammatory hyperplasias are lesions extremely common in the oral cavity. Nevertheless, in the literature there are different characteristics observed during the histopathologic diagnostic of this lesion. The aim of this study was to describe the microscopic characteristics observed in the inflammatory hyperplasia diagnosticated in the Oral Pathology Lab of the Federal University of Rio Grande do Sul (UFRGS), and recommend histologicals criteria for the diagnostic of this pathology. Twenty-five cases of inflammatory hyperplasia archived in the Oral Pathology Lab of the UFRGS were examinated between january and july of 2001. We concluded that the presence of cronic inflammatory infiltrated, epitelial hyperplasia and the uniform direction of the collagen fibers were the histological caracteristics finding in the majority of the lesions.
