Multicentric tracheobronchial and oesophageal granular cell myoblastoma.

Abstract
Two patients with multiple intrathoracic granular myoblastomas are described. In one case multiple tumors were present in the major airways and esophagus. The patient presented with recurrent pulmonary infections and stridor due to airway obstruction. In the other case dysphagia caused by multiple esophageal granular cell myoblastomas was the major symptom. Granular cell myoblastoma is a rare tumor of neurogenic origin with a characteristic histological appearance. The pattern of multiple tracheobronchial and esophageal tumors is uncommon and forms the basis of this report.
