原发性肺绒毛膜癌是一种高度侵袭性的生殖细胞肿瘤，极其罕见，尤其是在男性中。其特点是对治疗反应不佳和生存时间缩短。我们介绍一名 46 岁男性原发性肺绒毛膜癌病例。患者因咳嗽、呼吸困难和咯血加重而被转至我院。胸部增强计算机断层扫描显示左下肺有一个强烈增强的 15 × 14 cm 大小的结节性病变，并侵入膈肌。肋间动脉栓塞后，肿瘤成功切除。然而，患者在手术后第28天突然死亡。尸检结果显示，他的死因是右冠状动脉肿瘤栓塞。© 2024 作者。约翰·威利 (John Wiley) 出版的呼吸病学病例报告

Primary pulmonary choriocarcinoma is a highly aggressive germ cell neoplasm and an extremely rare, especially in males. It is characterized by a poor response to therapy and shortened survival times. We present the case of primary pulmonary choriocarcinoma in a 46-year-old male. The patient was referred to our institute with cough, worsening dyspnea and hemoptysis. The contrast-enhanced chest computed tomography revealed an avid enhanced 15 × 14 cm sized nodular lesion, in the left lower lung, which invaded into the diaphragm. After the embolization of the intercostal arteries, the tumour was resected successfully. However, the patient had died suddenly on the 28th day after the surgery. Autopsy was conducted and revealed that his cause of the death was the tumour emboli in the right coronary artery.© 2024 The Author(s).
