Histopathological aspects of benign epithelial tumors located in areas of friction or chronic irritation of the tongue.

Besides lesions considered to be premalignant (such as erythroplasia, Bowen disease), a number of other potentially malignant lesions with higher or lower degree of epithelial dysplasia depending on the keratinization degree or determined by the action of carcinogens and irritants substances are described in the oral mucosa. Although they are practically considered the most harmless formations located on the oral mucosa, papillomas and condylomas are also the most frequent. In this study (conducted on a total of 38 cases with benign neoplasia) we planned a histopathological evaluation of surgical excision samples obtained from interventions on lingual neoplasias and harvested from the areas most exposed to chronic trauma or the areas in direct contact with mechanical irritants, in order to determine the histopathological pattern of the different types of histopathological lesions, the possible presence of keratosis-type changes or even possible dysplasias.
