Abstract
We report a case of maxillary gingival metastasis from lung cancer, the first symptom of which occurred in an oral cavity.
The patient was an 80-year-old man. On his initial visit, a soft elastic mass, with an 18mm diameter, was on his right maxillary gingiva. A biopsy revealed the lesion was a large cell carcinoma. Since the large cell carcinoma is less likely to firstly occur in the gingiva, we inspected the whole body of the patient. As a result, tumors were found in the upper left lung, stomach and brain. The metastatic gingival tumor increased rapidly after the biopsy. We conducted concurrent chemoradiotherapy using S-1 with a total dose of 38.4Gy irradiation to the oral and brain lesion. This treatment reduced the maxillary gingival tumor. He died from a stroke; however, due to reduction of the gingival tumor, he could continue to have oral nutrition until immediately before his death.
It was suggested that we should consider palliative chemoradiotherapy for a maxillary gingival metastasis, even if it was impossible to cure the patient to maintain his Quality of Life.
