A bronchial hamartoma falls under the same spectrum of pathology as a pulmonary hamartoma (except for their location). An endobronchial location is less common than than a peripheral pulmonary location where thay only account for around 1.4-10% of all intrathoracic hamartomas.

Epidemiology

The mean age of the patient at presentation ranges around the 6^th to 7^thdecades. There may be a slight male predominance.

Pathology

As with other hamartomas, they are comprised of mature cartilage and fat elements with muscle and bone elements also present in some cases.

Variants

endobronchial lipomatous hamartoma ^4-5

Treatment and prognosis

Although they are benign they can be associated with bronchial obstruction and bleeding on some occasions. Endoscopic treatment with rigid bronchoscopy and lasers provides an excellent outcome and can be offered in patient's having lesions which can causes obstruction.
