Despite improved screening modalities, 15-25% of newly diagnosed colorectal cancers are metastatic at the time of diagnosis. The vast majority of these cases present as hepatic metastasis; however, 22% present with concomitant extrahepatic disease. The thymus gland is an uncommon site of metastasis for any primary malignancy, particularly, colorectal cancer given its vascular and lymphatic drainage. This case report details our experience with a rare case of colorectal cancer metastasis to the thymus gland presenting as a symptomatic mediastinal mass.
尽管筛查方式有所改进，但仍有15%-25%新诊断的结直肠癌在确诊时已发生转移。这些病例绝大多数表现为肝转移；然而，22%伴有肝外疾病。胸腺是任何原发性恶性肿瘤罕见的转移部位，尤其是结直肠癌，考虑到其血管和淋巴引流情况。本病例报告详细介绍了我们处理的一例罕见的结直肠癌转移至胸腺并表现为有症状纵隔肿块的经验。
