Hamartomas are benign mesenchymal neoplasms containing tissues made up of cartilage, smooth muscle, and connective tissue. They occur in the trachea, bronchi, and the lung parenchymal tissues and are said to be the most common benign tumors of the lung. Hamartomas, particularly the intraparenchymal variants, are clinically silent in the majority of cases. However, the endobronchial ones present with varying degree of respiratory distress, depending on the degree of luminal obstruction. They often present on chest radiographs as solitary pulmonary nodules, ranging in size from less than 2 to 5 cm or more. The nodules are frequently calcified and show the typical “popcorn” appearance, owing to their lobulated contours. On computed tomography, fat or fat with calcification can be detected.
