Lung hamartoma resembling lung cancer: a report of three cases.

Pulmonary hamartoma is a benign lung tumor. However, it is difficult to distinguish this lesion from other diseases imaging. Three patients with pathologically confirmed pulmonary hamartoma in our department were analyzed. We believe it is necessary to combine imaging, pathology, clinical testing, and individual patient assessments to enable an earlier and more definitive diagnosis of pulmonary hamartoma. Therefore, it is necessary to analyze and summarize the clinical manifestations and imaging features of patients with pulmonary hamartoma to improve the early recognition of the disease by clinicians.
