Intrabony oral non-Hodgkin lymphoma (NHL) is rare. We report 2 cases of NHL of the maxilla that initially presented as apical abscesses in endodontically treated teeth. Radiographic findings were nondescript, but tissue biopsy revealed diffuse large B-cell NHL in both instances. No other sites of disease were found. Both patients were treated by chemotherapy and radiation with good results. As primary NHL of the maxilla can mimic a dental inflammatory lesion, tissue biopsy is mandatory in cases where symptoms do not resolve after specific treatment.
