Metastatic tumours involving the head and neck region are rare. Over the past 18 years, seven such cases were treated at our clinic. Of those, four were in one of the paranasal sinuses, three had arisen from a primary hepatocellular carcinoma and one from an osteogenic fibrosarcoma of the leg. In the remaining three cases, metastases to the larynx, the tonsil, and the parotid gland arose from a primary renal cell carcinoma, a thyroid carcinoma, and a breast carcinoma, respectively. In metastatic tumours, the primary site can often be identified by the histopathological features. Accordingly, when malignant head and neck tumours are suspected of being metastatic in character, it is important to search carefully for the primary site.
累及头颈部区域的转移性肿瘤较为罕见。在过去18年里，我们诊所共治疗了7例此类病例。其中，4例发生于鼻窦之一，3例原发于肝细胞癌，1例原发于腿部的骨化性纤维肉瘤。其余3例中，转移至喉、扁桃体和腮腺的肿瘤分别原发于肾细胞癌、甲状腺癌和乳腺癌。在转移性肿瘤中，原发部位通常可通过组织病理学特征来确定。因此，当怀疑头颈部恶性肿瘤具有转移性时，仔细寻找原发部位非常重要。
