title: [Endobronchial granular cell tumor. A report of two cases in the course of staging of ORL cancers].
abstract: 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.
