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.
颌骨内口腔非霍奇金淋巴瘤（NHL）较为罕见。我们报告2例上颌骨NHL，最初表现为根管治疗牙齿的根尖脓肿。影像学表现不具特异性，但组织活检在两例中均显示为弥漫性大B细胞NHL。未发现其他疾病部位。两名患者均接受了化疗和放疗，效果良好。由于上颌骨原发性NHL可模仿牙齿炎性病变，因此在经过特定治疗后症状仍未缓解的病例中，组织活检是必不可少的。
