Pulmonary Hamartomas: A Single-Center Analysis of 59 Cases

Objective: This study investigated the clinical, radiological, and surgical treatment results of patients who underwent surgical treatment for pulmonary hamartomas. Materials and Methods: Fifty-nine consecutive patients who underwent surgical treatment for pulmonary hamartomas in our clinic between January 2001 and February 2021 were analyzed retrospectively. Results: Forty-three out of 59 (72.9%) of the cases were male and 16 (27.1%) were female. The average age was 52.0 +/- 15.0 (between 5 years and 80 years). While pulmonary hamartoma was in the form of a solitary pulmonary nodule in 55 (912%) of the cases there were multiple lesions in 4 (6.8%) cases. Simultaneous gastric adenocartinorna was detected in I patient. One case had been operated on for Wilms tumor. Twenty-two (37.3%) of the cases were asymptomatic and were detected incidentally. Locations of pulmonary hamartomas were 18 (29.0%) in the left lower lobe, 16 (25.8%) in the right upper lobe, 12 (19.4%) in the right lower lobe, 9 (14.5%) in the left upper lobe, and 7 (11.3%) in the right middle lobe. The mean lesion diameter was 22.0 +/- 95 mm (between I 0 mm and 56 mm). Mild to moderate fluorodeoxyglucose (FDG) uptake was observed in 11 of 15 cases that were evaluated with positron emission tomography/computed tomography. Surgically, 14 (74.6%) patients underwent wedge resection, 13 (22.0%) patients underwent enucleation and two (3.4%) patients underwent lobectomy. Perioperative morbidity and mortality were not observed in any of the cases. The cases were followed up for an average of 40.6 +/- 38.7 months (between I month and 151 months). No recurrence was observed in any of the cases during follow-up. Conclusion: Pulmonary hamartomas are usually detected incidentally and as a solitary pulmonary nodule. Although radiological findings provide important information, a definitive diagnosis is usually made during surgery. Parenchyma-sparing surgery should be preferred in these cases whenever possible.
