[Non-Hodgkin lymphoma with primary location in the oral cavity, extranodal variety. Report of a case].

Non-Hodgkin lymphomas with primary localization in the oral cavity are a relatively rare nosological entity which is difficult to diagnose and is generally accompanied by a fatal prognosis. The authors describe a case referred to their attention that presented symptoms such as paresthesia to the lower half lip, local tumefaction, etc, easily attributed to the recent extraction of 3.7. The fact that prompted them to investigate further was precisely the clinical and radiological characteristics which, even if vague, are indicative of non-Hodgkin lymphoma with an oral localization. The authors also examine and discuss the staging techniques and type of polychemotherapy used in this case.
