Abstract

Non-Hodgkin's lymphoma (NHL) is a lymphoproliferative disorder, from a subgroup of heterogeneous hematologic malignancies; the term "extranodal" refers to malignant involvement of tissues other than lymph nodes, tonsils, spleen, pharyngeal lymphatic ring, or thymus. Only 0.6% of all NHL are at mandible alone, and it may involve the inferior alveolar canal. We describe a case of bilateral enlargement of the mandibular canal without symptomatology, which was shown in a panoramic radiograph and cone beam computed tomography in a rehabilitation routine exam, as an early sign of primary extranodal NHL.

摘要

非霍奇金淋巴瘤（NHL）是一种淋巴增殖性疾病，属于异质性血液系统恶性肿瘤的一个亚组；“结外”一词指的是除淋巴结、扁桃体、脾脏、咽淋巴环或胸腺以外的组织发生恶性病变。在所有NHL中，仅0.6%的病例单独累及下颌骨，且可能累及下牙槽管。我们描述了一例下颌管双侧肿大但无临床症状的病例，该病例在一次康复常规检查的全景X线片和锥形束计算机断层扫描中显示，为原发性结外NHL的早期征象。
