In the upper respiratory-digestive tract cancer is always primary. Such cancer is very common, but other extremely rare secondary cancers may be found.
We studied our own patients and some published in the literature: cancer of the kidney with metastases in the paranasal sinuses and cancer of the breast metastasizing to the temporal bone. We review the bibliography on these rare metastases.
In all cases of otorhinolaryngological cancer a detailed history should be taken, with special reference to previous neoplasms. It is particularly important to study and review any history of renal, breast or prostate tumors with regard to the primary tumor and the receptor organs of metastases, the paranasal sinuses and temporal bones. The most difficult problem occurs when the primary tumor is present but undiagnosed. Therefore, in all cases of cancer of the paranasal sinuses and temporal bones, before treatment is started the kidney, prostate, breast and other organs above and below the diaphragm where tumor may be present should be examined. The prognosis of these metastases, which are almost always fatal, is very poor so that often treatment is only palliative rather than aggressive.
在上呼吸道 - 消化道中，癌症通常是原发性的。这类癌症很常见，但也可能发现其他极为罕见的继发性癌症。
我们研究了我们自己的患者以及文献中发表的一些病例：肾癌转移至鼻窦，乳腺癌转移至颞骨。我们回顾了关于这些罕见转移瘤的文献。
对于所有耳鼻喉科癌症病例，都应详细询问病史，特别提及既往肿瘤情况。研究和回顾任何肾脏、乳腺或前列腺肿瘤病史，对于原发性肿瘤以及转移瘤的受体器官——鼻窦和颞骨而言尤为重要。当原发性肿瘤存在但未被诊断时，最困难的问题就出现了。因此，对于所有鼻窦和颞骨癌症病例，在开始治疗前，应检查肾脏、前列腺、乳腺以及横膈膜上下其他可能存在肿瘤的器官。这些转移瘤的预后几乎总是致命的，非常差，所以治疗往往只是姑息性的而非积极的。
