A 48-year-old man with ASA status I who had been diagnosed with a right-side pulmonary hamartoma
was scheduled for a thoracoscopic pulmonary wedge resection under general anesthesia.

The identification of fat attenuation within a smooth or lobulated SPN on thin-section CT is diagnostic of a pulmonary hamartoma (Figure 6).
These are central, laminated, or diffuse calcification as seen within granulomas, and popcorn calcification seen in pulmonary hamartomas (Figure 3).

This factor is known to play a significant role in the frequent misdiagnoses of pulmonary hamartoma
(18) and in rare cases of pulmonary sequestration (15); in both lesions, the culprit is the abundant benign cohesive epithelium often misinterpreted as well-differentiated adenocarcinoma.
Benign lung tumors in the differential diagnosis include clear cell tumor, pulmonary hamartoma
, and hemangioma.
Thirty-eight cases of pulmonary hamartoma
resected by wedge resection or lobectomy were identified from departmental records.
The reasons for surgery in the control group were bullae in 10 cases, sequel lesions in 8 cases, and pulmonary hamartomas
in 2 cases.
are common benign tumors often located within the peripheral lung parenchyma.
While a hamartoma is defined as disordered growth of tissues normally present within the organ, pulmonary hamartomas
are clonal proliferations and therefore neoplastic.
