Lymphomas are rare pathologies in the oral cavity, representing only 3.5% of malignant tumors. Their typical topography is Waldeyer's lymphatic ring and approximately 8% of all non-Hodgkin lymphomas are mucosa associated lymphoid tissue (MALT) lymphomas. The authors report a rare case of mandibular gingival MALT lymphoma, which developed around an extraosseous dental root canal overfill. This atypical, case of lymphoma indicates that practitioners have to be vigilant and perform a biopsy every time they are confronted with a suspicious chronic lesion in the oral cavity.
口腔淋巴瘤较为罕见，仅占恶性肿瘤的 3.5%。其典型的解剖位置是瓦尔德叶尔（Waldeyer）淋巴环，约 8%的非霍奇金淋巴瘤为黏膜相关淋巴组织（MALT）淋巴瘤。作者报告了一例罕见的下颌牙龈 MALT 淋巴瘤，该肿瘤发生于牙槽骨外根管超填周围。这种非典型的淋巴瘤病例表明，临床医生每次在口腔中遇到可疑的慢性病变时都必须保持警惕并进行活检。
