Lung cancer metastatic to the maxillary gingiva—a case report and literature review

Summary Lung cancer metastatic to the gingiva is quite unusual. A total of 16 cases have been previously described in the English language medical literature. The case of a 49 year-old man with stage IV pulmonary adenocarcinoma is described in which two rapidly growing tumors with intermittent bleeding and tenderness were found over the maxillary gingiva during chemotherapy treatment. An excisional biopsy was performed and the presumptive diagnosis of metastatic adenocarcinoma was confirmed. Oral function, nutritional status, and quality of life improved after surgery.
