<p>Lymph node metastasis, in which the pathological diagnosis is inconsistent with lung cancer lesions, may lead to the discovery of other intrapulmonary lesions. Conversely, there are no reports of cases in which oropharyngeal cancer was discovered after lymph node metastasis was diagnosed in the hilar lymph nodes. The patient was a 73-year-old man. Chest computed tomography revealed a mass at the base of the right lung, and transbronchial lung biopsy revealed adenocarcinoma. Lower lobectomy of the right lung and lymph node dissection were conducted. Histopathological examination revealed that the tumor was an adenocarcinoma, but the right main peribronchial lymph node (#Rt10) showed a squamous cell carcinoma (SCC). Postoperative fiberoptic laryngeal examination revealed a neoplastic lesion on the lateral wall of the right middle pharynx. Biopsy results confirmed the diagnosis of moderately to highly differentiated SCC; therefore, lumpectomy was performed. Histopathological examination revealed a morphologically similar lesion to #Rt10. Although it is straightforward to determine multiple lung cancers due to discrepancies between the pathological diagnosis of a tumor and lymph node metastasis, there are few reports of multiple cancers found in other organs, as in the present case. Preoperative diagnosis of patients at high risk of cancer should be performed more cautiously.</p>
