Gingival metastasis of adenocarcinoma from the lung

SummaryMetastases to the gingival soft tissues are extremely rare. We report a case of a lung tumor metastatic to the mandibular gingiva. A 66-year-old woman complained of dizziness and a tumor in the lower gingiva. Magnetic resonance imaging (MRI) of the brain revealed multiple brain tumors, and computed tomography (CT) of the lung showed a mass in the left lower lobe. Histological diagnoses from biopsies of the brain, lung and gingiva were adenocarcinoma of the lung with multiple metastases to the brain and gingiva. Radiographic examination revealed that the bone underlying the gingival metastasis was not involved.
