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.
