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.
摘要：
肺肿瘤栓塞(PTE)主要由腺癌引起。然而,仅报道了少数口咽癌病例。我们在此报告一名47岁的男子，他发烧，咳嗽,治疗II期口咽癌6个月后呼吸困难。胸部计算机断层扫描显示小叶中心颗粒和结节状阴影以及胸膜下实变。经支气管肺活检显示在小血管中有大量鳞状肿瘤细胞形成栓子，导致口咽肿瘤的PTE诊断。因此,有缺氧史的患者应考虑PTE。
