摘要

This is a retrospective study that reviewed 235 malignant cases of the oral and maxillo-facial region in Okayama University Hospital attached to Dental School between April 1982 and March 1988, of these it was found 6 cases of metastatic tumors to the mouth and jaws from a distant area. Malignant tumors of the lung provided the largest number of mouth and jaw metastasis in our series, the appearance of the lesions was as that of adenocarcinomas. Six patients were ranging in age from 42 to 82 years, and 3 were males and 3 were females. The most frequent symptoms observed were swelling and pain. Metastasis to the jaw bones were found predominantly in the mandible, and metastasis to the oral soft tissue occurred in two cases. Metastasis to the mandibular molar region radiographically showed central bone destruction, and metastasis to other regions showed peripheral bone destruction. Biopsy and radionuclide examinations were very useful for diagnosis of the metastatic tumors to the oral and maxillo-facial region.
