{Abstract}: Pulmonary tumor embolisms (PTEs) are primarily caused by adenocarcinoma. However, only a few cases of oropharyngeal carcinoma have been reported. We herein report a 47-year-old man who presented with a fever, cough, and dyspnea 6 months after treatment for stage II oropharyngeal carcinoma. Chest computed tomography revealed centrilobular granular and nodular shadows and subpleural consolidation. A transbronchial lung biopsy revealed a mass of squamous tumor cells forming emboli in the small vessels, resulting in the diagnosis of PTE due to oropharyngeal carcinoma. Therefore, PTE should be considered for patients with a history of hypoxia.
