The current study presents a rare case of small cell lung cancer (SCLC) with endobronchial growth in a 68-year-old male. Chest CT scans revealed an ill-defined mass in the upper lobe of the right lung, with ipsilateral mediastinial lymph node swelling. An endobronchial polypoid tumor in the right B3 bronchus was located by bronchoscopic examination. The analysis of a biopsy specimen obtained from the tumor resulted in a diagnosis of SCLC. Although extremely rare, this case highlights the importance of considering a diagnosis of SCLC in patients presenting with a pulmonary tumor adjacent to the bronchus, with an endobronchial polypoid lesion.
本研究报告了一例罕见的小细胞肺癌（SCLC）病例，患者为一名68岁男性，肿瘤呈支气管内生长。胸部CT扫描显示右肺上叶有一个边界不清的肿块，同侧纵隔淋巴结肿大。通过支气管镜检查发现右B3支气管内有一个息肉样肿瘤。对肿瘤活检标本的分析结果确诊为小细胞肺癌。尽管极为罕见，但该病例凸显了对于出现支气管旁肺部肿瘤且伴有支气管内息肉样病变的患者，考虑小细胞肺癌诊断的重要性。
