Secondary tumours of small intestine account for 10% of all small bowel cancers. The most common sites of primary tumour metastasizing to small bowel are uterus, cervix, colon, lung, breast and melanoma. The majority of these metastatic tumours come from adenocarcinoma primaries; squamous cell carcinoma constitutes a very small proportion of all metastatic small intestinal lesions. Metastasis to small bowel by head and neck squamous cell carcinoma is extremely rare and carries an unfavourable prognosis. Owing to the limited number of published studies, its characteristic features, clinical presentation and outcomes are poorly described. This work aims at specifying these characteristics by reviewing, compiling, analysing and reporting all published cases in the published literature on small bowel metastasis secondary to head and neck squamous cell carcinoma. To the best of our knowledge, this is the first comprehensive review article on the small intestinal metastasis from head and neck squamous cell carcinoma.
小肠的继发性肿瘤占所有小肠癌的 10%。最常见的原发肿瘤转移到小肠的部位是子宫、宫颈、结肠、肺、乳房和黑色素瘤。这些转移性肿瘤大多数来自腺癌原发灶；鳞状细胞癌构成所有转移性小肠病变的很小一部分。头颈部鳞状细胞癌转移到小肠非常罕见，预后不良。由于发表的研究数量有限，其特征、临床表现和结果描述得很差。这项工作旨在通过回顾、编译、分析和报告发表文献中所有关于头颈部鳞状细胞癌继发于小肠转移的病例来明确这些特征。据我们所知，这是第一篇关于头颈部鳞状细胞癌小肠转移的综合综述文章。
