Brown tumors are uncommon focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone on bone tissue in some patients that have hyperparathyroidism. Primary hyperparathyroidism could be caused by ectopic mediastinal parathyroid adenomas. The occurrence of lesions is explainable on embryologic basis. We present a 55-year-old Saudi woman with a rare case of brown tumor of the maxilla due to ectopic mediastinal parathyroid adenoma.
棕色瘤是一种罕见的局灶性巨细胞病变,是甲状旁腺激素作用于某些甲状旁腺功能亢进患者的骨组织而直接产生的结果。原发性甲状旁腺功能亢进可能由纵隔异位甲状旁腺腺瘤引起。病变的发生在胚胎学基础上是可以解释的。我们报告一例55岁沙特女性,因纵隔异位甲状旁腺腺瘤导致上颌骨棕色瘤,此病例罕见。
