Abstract

An 81-year-old woman with a 2-year history of dysphagia detected a cervical mass. Computed tomography showed a thyroid tumor extending through the superior and anterior mediastinum. Analysis of an incisional biopsy specimen revealed a thymoma. Total resection of the thyroid and mediastinal tumor was performed. The thymoma invaded the anterior tracheal wall and left brachiocephalic vein. Pathologic examination revealed thymoma type B1 concomitant with B2 and B3 (World Health Organization classification), Masaoka IVb, and T3 N2 M0-IVb, with cervical lymph node metastasis. Clinicians must be cautious during radical operations for invasive ectopic thymomas.

摘要

一位 81 岁女性，2 年前出现吞咽困难，发现颈部肿块。计算机断层扫描显示甲状腺肿瘤延伸至上纵隔和前纵隔。切开活检标本分析显示胸腺瘤。行甲状腺和纵隔肿瘤全切除术。胸腺瘤侵犯前气管壁和左头臂静脉。病理检查显示胸腺瘤 B1 型伴 B2 和 B3（世界卫生组织分类），Masaoka IVb，以及 T3 N2 M0-IVb，伴有颈部淋巴结转移。对于侵袭性异位胸腺瘤的根治性手术，临床医生必须谨慎。
