Hamartomas represent 4% to 8% of all solitary pulmonary nodules,
2
which present themselves as well-circumscribed, asymptomatic coin lesions within the pulmonary parenchyma.
3
Usually they are chondromatous hamartomas consisting of cartilage and are regarded as benign neoplasms derived from the peribronchial mesenchymal tissue. Symptoms such as cough, hemoptysis, or pulmonary infections arise only when the location is endobronchial, which is rare (10%). There is an overall incidental finding in approximately 0.25% of autopsies, and hamartomas are found more frequently in men than in women (2:1).
