Pulmonary hamartoma: Retrospective analysis of 24 cases

Abstract

Objective: Lung hamartoma is the most frequently diagnosed benign lung tumor. The aim of this study was to investigate the clinical, radiological and pathological data of the patients with pulmonary hamartoma who underwent surgical treatment in our clinic. Methods: Hospital records of 24 lung hamartoma patients given surgical treatment in our clinics between January 2005 and December 2017 were investigated retrospectively. In this study, these cases were evaluated with respect to age, gender, clinical, histopathological, and radiological features, and surgical methods. Results: There were 24 patients with a mean age of 50.6 (23-66) years, consisting of 14 males and 10 females, who underwent surgical resection for pulmonary hamartoma was. While 17 (42%) patients were asymptomatic, the rest complained of coughing, shortness of breath and repetitive lung infections. Hamartoma was localized in the right lung in 16 (67%) of the cases; peripherally in 17 (71%), and centrally in 7 (29%). All patients underwent wedge resection, 17 cases by thoracoscopy and 7 cases by thoracotomy. The mean tumor diameter assessed macroscopically was 2.9 cm (1-4.5cm). Conclusion: Pulmonary hamartomas frequently present as peripheral solitary nodules. Given its low morbidity and mortality, surgical resection is recommended for definitive diagnosis and treatment, the objective of the intervention being total excision of the lesion while protecting the lung parenchyma.
