Rare Anterior Tongue Metastasis from Primary Lung Cancer: A Case Report
肺腺癌合併舌部轉移－病例報告
並列摘要
Primary tumors metastasizing to the tongue are extremely rare. There is a 1% rate of metastasis to the oral cavity from other primary sites, most commonly the lung, breast, skin, gastrointestinal tract, and liver. There is a 1.6% rate of primary lung cancer metastasized to the tongue. We describe a patient with adenocarcinoma of the lung who developed a metastatic lesion on the tongue. A 71-year-old Taiwanese male was diagnosed with adenocarcinoma of the lung at stage IV (cT4N2M1a, stage IV [lung-to-lung metastasis]) with a tongue tumor. The tumor was painful, palpable, and firm, measuring around 1 x 1 x 1 cm^3 on the anterior part of the tongue. There was no cervical lymphadenopathy. The tumor was thought to be a metastasis of the lung adenocarcinoma. The tongue lesion was excised and revealed adenocarcinoma. The histology of the specimen was consistent with that of the previous lung cancer, so he was considered to have had tongue metastasis from adenocarcinoma of the lung (right upper lung, cT4N2M1b, stage IV [lung-to-lung and tongue metastasis]).
