TUMORS METASTASIZING TO THE HEAD AND NECK - A REPORT OF 7 CASES

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.
