A 36-year-old man was diagnosed as a case of mucinous adenocarcinoma of the rectum, Dukes' C. Pathologic examination revealed abundant signet-ring cells in the tumor. He did not receive adjuvant radiotherapy or chemotherapy after resection of the tumor. Two years later, a 3 x 5 cm mass over the right palatine tonsil was found with associated right neck lymphadenopathy. Right tonsillectomy was performed. Metastatic mucinous adenocarcinoma of the tonsil with abundant signet-ring cells similar to the primary tumor of the rectum was found. Signet-ring cell carcinoma of the rectum with tonsillar metastasis is extremely rare. No case has been reported in the English literature. To the best of our knowledge, this is the first case of signet-ring cell carcinoma of the rectum with tonsillar metastasis. The relevant literature on metastatic tonsillar tumors is reviewed.
一名36岁男性被诊断为直肠黏液腺癌，Dukes' C期。病理检查显示肿瘤中有大量印戒细胞。肿瘤切除后，他未接受辅助放疗或化疗。两年后，在右侧腭扁桃体发现一个3×5 cm的肿物，并伴有右侧颈部淋巴结肿大。遂行右侧扁桃体切除术。病理发现扁桃体转移性黏液腺癌，伴有大量印戒细胞，与直肠原发肿瘤相似。直肠印戒细胞癌伴扁桃体转移极为罕见。英文文献中尚无相关病例报道。据我们所知，这是首例直肠印戒细胞癌伴扁桃体转移的病例。本文对扁桃体转移性肿瘤的相关文献进行了综述。
