It has become increasingly appreciated that, although rare, a supernumerary (fifth) parathyroid gland may be a cause of excess parathyroid hormone production. This review reports 15 patients, each of whom had hyperparathyroidism as a consequence of such a hyperfunctioning fifth gland. It is apparent that these patients are similar to the usual patients with primary hyperparathyroidism with respect to complications of the disease, type of pathology, and care after surgical excision of the abnormal parathyroid tissue. Significantly different, however, is the fact that the majority of these fifth-gland tumors were located in the mediastinum. The circumstances under which a supernumerary gland should be expected and the recommended surgical approach are reviewed.
人们越来越认识到，虽然罕见，但额外的（第五个）甲状旁腺可能是甲状旁腺激素分泌过多的一个原因。本综述报告了15例患者，每例患者因这种功能亢进的第五个腺体而患有甲状旁腺功能亢进。显然，这些患者在疾病并发症、病理类型以及异常甲状旁腺组织手术切除后的护理方面与原发性甲状旁腺功能亢进的普通患者相似。然而，显著不同的是，这些第五个腺体肿瘤大多数位于纵隔。本文对预期出现额外腺体的情况以及推荐的手术方法进行了综述。
