Endobronchial chondromas.

Endobronchial chondromas are rare benign tumors. They may be part of the Carney triad; however, isolated endobronchial chondromas can occur in the larynx, trachea, and bronchi. We report a case of an endobronchial chondroma in a 61-y-old man with an incidental 5-mm endobronchial polypoid lesion at the proximal left main bronchus that was later found to be an endobronchial chondroma. Flexible bronchoscopy demonstrated a pedunculated, vascularized, pink mass. An excisional biopsy revealed a well-circumscribed lesion with nodular areas of mature cartilage and myxoid tissue confirmatory of an endobronchial chondroma. We reviewed a total of 23 cases of isolated endobronchial chondromas reported in the medical literature. Despite their rarity, endobronchial chondromas should be considered in the differential diagnosis of endobronchial tumors. Prompt recognition and resection of endobronchial chondromas is important to prevent airway obstruction and its associated complications.
