Primary tracheal tumors are very rare and the literature on this subject is limited. The most common histological type of primary tracheal tumors is squamous cell carcinoma (SCC), followed by adenoid cystic carcinoma (ACC). Limited knowledge exists regarding the behavior and outcomes of different histological types of tracheal cancers. The present study aimed to address this gap by assessing the significance of the histological type of primary tracheal tumors based on our own data and to review the literature.

原发性气管肿瘤89例临床病理特征分析

原发性气管肿瘤非常罕见，有关该主题的文献也很有限。原发性气管肿瘤最常见的组织学类型是鳞状细胞癌（SCC），其次是腺样囊性癌（ACC）。关于不同组织学类型的气管癌的行为和结果的知识有限。本研究旨在通过根据我们自己的数据评估原发性气管肿瘤组织学类型的重要性并回顾文献来解决这一差距。
