Oral mucosa neoplasms are most often pre-malignant lesions that evolved in squamous cell carcinoma (90% of cancers of the oral cavity). Tobacco and alcohol are the two most incriminated etiological factors. Other etiologies have also been mentioned, in particular the oncogenicity of certain viruses like the human papillomavirus (HPV). However, other types of cancer may occur mainly in young adults whose starting point is generally a salivary gland (10% of cancers of the oral cavity). From two clinical cases, squamous cell carcinoma and mucoepidermoid carcinoma, we describe the etiopathogenesis and the clinical characteristics as well as the histopathological particularities, diagnosis and prognosis of each of these entities. We also developped the interest of an early detection of the lesions that will provide the patient a better prognosis even though the therapeutic strategy is established in the best conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
