We report two new observations of endobronchial granular cell tumor discovering by bronchoscopy, during the staging of head and neck cancers. This site remains exceptional; the histologic features are well known. The ultrastructural and especially the immunohistological criteria trend to indicate a neurogenic histogenesis. Although the course is benign in this site and no malignant forms have been reported, local relapses are possible. However, some benign cases may have disturbing endoscopic and histologic features.
我们报告了两例在头颈部癌症分期过程中通过支气管镜检查发现的支气管内颗粒细胞瘤新病例。该部位仍然较为罕见；其组织学特征是众所周知的。超微结构尤其是免疫组织化学标准倾向于表明其神经源性组织发生。尽管该部位的病程是良性的且尚未报告有恶性形式，但局部复发是可能的。然而，一些良性病例可能具有令人困扰的内镜和组织学特征。
