HISTORY AND PRESENTATION AT ADMISSION: An 82-year-old male patient presented with a 3 week history of exercise-induced dyspnea, productive cough and left sided chest pain.
Computertomography of the chest revealed an occluding endobronchial tumor in the left main bronchus with enlarged mediastinal lymph nodes, mediastinal shift and post-stenotic peribronchitis.
The tumor was removed completely with an optical forceps in rigid bronchoscopy. Histologically an endobronchial sialadenoma papilliferum was diagnosed.
Benign tumors of the lower airways are rare. They cannot be distinguished reliably from malignant tumors by their endoscopic and radiologic appearance. Sialadenoma papilliferum is an extremely rare benign salivary gland tumor which is characterized by coexisting glandular and (pseudo) papillar formations. It occurs mainly in the oral cavity. The relapse rate is 10-15%. In single cases a malignant transformation may appear.
入院时的病史及表现：一名82岁男性患者，有3周运动性呼吸困难、咳痰和左侧胸痛病史。
胸部计算机断层扫描显示左主支气管内有一阻塞性支气管内肿瘤，伴有纵隔淋巴结肿大、纵隔移位和狭窄后支气管周围炎。
在硬质支气管镜检查中用光学活检钳将肿瘤完全切除。组织学诊断为支气管内乳头状涎腺瘤。
下呼吸道良性肿瘤罕见。通过内镜和放射学表现无法可靠地区分它们与恶性肿瘤。乳头状涎腺瘤是一种极其罕见的良性涎腺肿瘤，其特征是同时存在腺性和（假）乳头状结构。它主要发生在口腔。复发率为10% - 15%。个别情况下可能会出现恶性转化。
