A case of spontaneous regression of malignant lymphoma of the maxillary gingiva following a biopsy is reported. An 84-year-old man was referred to the hospital with chief complaints of swelling of the anterior maxillary gingiva. A non-tender swelling with an ulcer was observed. There was no abnormal bone resorption in the anterior maxillary region and no swelling of the cervical lymph nodes. A biopsy was performed, and the patient was diagnosed with diffuse large B-cell lymphoma. The lesion regressed spontaneously 3 weeks after the initial biopsy. Two years have passed since the spontaneous regression and no recurrence has been observed. If malignant lymphoma regresses on biopsy, observation is considered to be sufficient.
报告一例上颌牙龈恶性淋巴瘤自发消退病例。一名 84 岁男性因上颌牙龈肿胀就诊。观察到一处无触痛性肿胀伴溃疡。上颌前区无异常骨吸收，颈部淋巴结无肿胀。行活检后，患者被诊断为弥漫性大 B 细胞淋巴瘤。初次活检后 3 周，病变自发消退。自发消退后 2 年，未见复发。如果恶性淋巴瘤在活检时消退，则认为观察是足够的。
