Abstract
Three cases of the metastatic tumors to the oral regions from primary malignant tumors of other organs encountered in our clinic in the last 16 years were reported. Those three cases constituted 1.7% of the malignant tumors of the oral regions treated in our clinic during the same period.
The first case was a 74-year-old man with adenocarcinoma of the prostate gland which metastasized to the mandibular bone. In this case, oral metastatic lesion had been detected before the prostatic carcinoma was diagnosed. Panoramic radiograph showed osteolytic change in the ascending ramus of the right mandible at the first visit, but only 2 weeks after castration calcification was recognized in the same region. And there were no tumor cells in the biopsy specimen of the right mandible one year after castration.
The second case was a 71-year-old woman with adenocarcinoma of the stomach which metastasized to the maxillary gingiva.
The third case was a 78-year-old man with epidermoid carcinoma of the esophagus (Im) which metastasized to the oropharynx.
