Endobronchial chondromatous hamartoma in an infant.

Hyperinflation or atelectasis of a lung or one of its lobes is generally due to partial or complete bronchial obstruction. Intramural large airway obstructive lesions or cysts are uncommon in the pediatric age group. They are usually discovered in the supraglottic or glottic areas. Primary pulmonary, tracheal, or bronchial tumors are very unusual in children. In this report, we describe an infant with an endobronchial chondromatous hamartoma obstructing the right main bronchus. This infant presented with cough, wheezing, and unilateral hyperinflation of the right lung. The patient’s symptoms improved after endoscopic resection of the endobronchial lesion.
