Bronchial hamartoma
Updates to Article Attributes
A bronchial hamartoma falls under the same spectrum of pathology as a pulmonary hamartoma (except for their location), but a hamartoma in an bronchial location is less common than a peripheral pulmonary location. Bronchial hamartoma accounts for only around 1.4-10% of all intrathoracic hamartomas.
Epidemiology
The mean age of patients at presentation ranges between the 6th to 7th decades. There may be a slight male predominance.
Pathology
As with other hamartomas, bronchial hamartomas are comprised of mature cartilage and fat elements, as well as muscle and bone elements also present in some cases.
Variants
Radiographic features
CT
Bronchial hamartomas typically contain fat (HU of -40 to -120), calcification (HU of >200), or a combination of both.
There may be associated distal lung collapse or airway dilatation.
Treatment and prognosis
Although bronchial hamartomas are benign they can be associated with bronchial obstruction and bleeding in some cases. Endoscopic treatment with rigid bronchoscopy and lasers provides an excellent outcome and can be offered in patient's with lesions causing obstruction.
