Atypical case of oral leukoplakia

Abstract

The oral leukoplakia is one of the most frequently found precancerous lesions found in the oral cavity. It is classified by OMS as being “a white pot or plate that cannot be clinically or pathologically classified as any other disease.” Its etiology is still controversial, but it seems to exist a narrow connection with chronic traumatisms, especially the prolonged use of the tobacco. Common localizations are: the red area of lips, jugal mucosa and gums. The aim of the present work was to present and discuss an unusual case of leukoplakia in a patient referred to the Center of Reference of Oral Lesions (CRLB) of the State University of Feira de Santana (UEFS). The report highlights the uncommon localization of the lesion and its previous erroneous diagnosis.
