We herein report a case of thymic carcinoma that initially exhibited dysphagia and an intraesophageal mass lesion. A 68-year-old man was admitted to our hospital because of dysphagia. An endoscopic examination revealed a mass on the middle esophagus. Chest computed tomography (CT) showed a huge anterior mediastinal mass and subcarinal lymph node swelling, directly invading into the esophageal lumen. An immunohistological examination of the esophageal and anterior mediastinal masses revealed squamous cell carcinoma originating from the thymus. This is the first report of a thymic carcinoma spreading into the esophageal lumen and forming a mass lesion.
我们在此报告一例胸腺癌病例,该病例最初表现为吞咽困难和食管内肿块病变。一名 68 岁男性因吞咽困难而被收入我院。内镜检查发现食管中段有一肿块。胸部计算机断层扫描(CT)显示巨大的前纵隔肿块和隆突下淋巴结肿大,直接侵犯食管腔。食管和前纵隔肿块的免疫组织化学检查显示源自胸腺的鳞状细胞癌。这是首例胸腺癌扩散至食管腔并形成肿块病变的报告。
