"Bronchial adenoma" formerly used to describe tumors arising in central airways (trachea and mainstem bronchi)
Included several central airway malignancies
Bronchial carcinoid
Adenoid cystic carcinoma
Mucoepidermoid carcinoma
Carcinoids are malignant; term "adenoma" is misnomer
Definitions
Low-grade malignant neuroendocrine neoplasm, rarely metastasizes to extrathoracic structures
Arises from neuroendocrine cells in tracheobronchial epithelium, histologically distinct from AC
Lung is 2nd most common location
90% of carcinoids occur in gastrointestinal tract
