The aim of this study is to report the case of a quick growing brown tumour in the jaw after a parathyroidectomy due to the presence of a rare fifth parathyroid gland. The patient had chronic renal disease and the diagnosis was tertiary hyperparathyroidism. Thirty days after the parathyroidectomy, the patient returned with a significant increase in the tumour size. The suspicion of a supernumerary gland was confirmed by parathyroid scintigraphy. The treatment of brown tumour is dependent on the treatment of the hyperparathyroidism. However, curettage should be considered if a large lesion is disturbing mastication. In conclusion, this case should attract the attention of general practitioner dentists, since they may be the first professionals who have contact with the patient with a brown tumour in the jaws. Likewise, this case emphasises the importance of knowing the type of hyperparathyroidism involved to allow for effective treatment planning.
本研究旨在报告一例甲状旁腺切除术后因罕见的第五个甲状旁腺而在颌骨中快速生长的棕色瘤病例。患者患有慢性肾病，诊断为三发性甲状旁腺功能亢进症。甲状旁腺切除术后 30 天，患者返回时肿瘤大小显著增大。甲状旁腺闪烁显像证实了副腺的存在。棕色瘤的治疗取决于甲状旁腺功能亢进症的治疗。然而，如果大的病变干扰咀嚼，应考虑刮除。总之，这种情况应该引起全科牙医的注意，因为他们可能是第一个与颌骨棕色瘤患者接触的专业人员。同样，这个病例强调了了解所涉及的甲状旁腺功能亢进症类型的重要性，以便进行有效的治疗计划。
