Most anterior mediastinal tumors are thymomas. Thymic metastasis from other primary cancers is extremely rare. We report the case of a 72-year-old man who developed thymic and mediastinal lymph node metastases of cecum cancer. He had undergone laparoscopic ileocecal resection with regional lymph node dissection for primary cecum cancer 15 months previously. Follow-up computed tomography revealed tumors in the anterior mediastinum. Fluorodeoxyglucose positron emission tomography showed positive uptake in the tumors. Because thymoma or thymic carcinoma was suspected, we performed total thymectomy via a median sternotomy. Histologic findings of the anterior mediastinal tumors were compatible with metastasis of the previously resected cecum cancer.
大多数前纵隔肿瘤是胸腺瘤。其他原发性癌症的胸腺转移极为罕见。我们报告一例72岁男性，发生了盲肠癌的胸腺及纵隔淋巴结转移。他在15个月前因原发性盲肠癌接受了腹腔镜下回盲部切除术及区域淋巴结清扫术。随访计算机断层扫描显示前纵隔有肿瘤。氟脱氧葡萄糖正电子发射断层扫描显示肿瘤有阳性摄取。由于怀疑是胸腺瘤或胸腺癌，我们通过正中胸骨切开术进行了全胸腺切除术。前纵隔肿瘤的组织学检查结果与先前切除的盲肠癌转移相符。
