Benign Endobronchial Granular Cell Tumor Resulting in Right Middle Lobe Collapse

Abstract

Granular cell tumors (GCTs) are generally benign neoplastic tumors of neural origin that have little malignant potential. These tumors may occur in any location, including the tracheobronchial tree. Although an endobronchial location is believed to represent a small percentage of cases, GCTs should be included in the differential considerations of any endobronchial lesions leading to airway collapse.
