摘要：Oral squamous cell carcinoma (OEC) is the most common type of malignant neoplasm among head and neck tumors, accounting for more than 90% of cases and, despite advances in therapeutic measures, most tumors are diagnosed at a late stage of the disease , resulting in poor prognosis and low survival rates. Disorders with potential for malignancy (MPD) are clinical and histopathological abnormalities, at the cellular level, which can assume the character of a malignant tumor at any time, but can remain stable for a considerable time. Literature points out that about 80% of oral cancers are progressions of MPD. Knowing the lesions with potential for malignancy becomes important for early diagnosis of oral cancer, improving prognosis and survival rates. Given the above, this study aims to review the literature on lesions with potential for malignancy, addressing their main characteristics that make it possible to identify them. For the construction of this article, a bibliographic survey was carried out in the SciVerse Scopus, Scientific Electronic Library Online (Scielo), Virtual Health Library (BVS) and U.S. National Library of Medicine (PUBMED) databases. Articles from 2010 to 2021 were selected. The results of this research show that there are four main lesions with great potential to become oral cancer, namely leukoplakia, erythroplasia, actinic kielitis and oral lichen planus.
