A case of cervical thymoma in a 51-year-old female is reported. The tumor was located on the left side of the anterior neck just beneath the left lower lobe of the thyroid gland and there was no connection to the mediastinal thymus gland. It was well encapsulated and lobulated on the cut-surface. Histologically, the tumor showed a mixed proliferation of lymphocytes and epithelial cells. Mitoses were frequently seen. Several tiny fragments of ectopic thymic tissue were found around the tumor. Cervical thymic tissue, considered to be the original site of the cervical thymoma, was studied and found macroscopically in 12 out of 657 patients with Basedow's disease (1.8%).
报告了一例51岁女性的颈部胸腺瘤病例。肿瘤位于颈前部左侧，恰好在甲状腺左叶下方，与纵隔胸腺无连接。肿瘤包膜完整，切面呈分叶状。组织学上，肿瘤表现为淋巴细胞和上皮细胞的混合增殖。可见频繁的核分裂象。在肿瘤周围发现了几个微小的异位胸腺组织碎片。对被认为是颈部胸腺瘤原发部位的颈部胸腺组织进行了研究，在657例巴塞多氏病患者中有12例（1.8%）在宏观上发现了该组织。
