Benign lung tumors are usually assymptomatic and do not pose a significant health problem. The purpose of surgical intervention for benign lung tumors is to avoid missing potentially malignant lesions. In some situations, these tumors can be diagnosed and treated endoscopically.

tumors of the lung

72 patients were included, 68% male,mean age 55 years.Most of the
patients were assymptomatic. In 23,6% of patients with endoscopic
abnormalities appeared respiratory symptoms such as shortness of breath
and obstructive pneumonia. CT scan showed a solitary pulmonary nodule
in 73,6%.Endoscopic abnormalities were found in 16 patients.Tumors were
more frequently located at main bronchus.Most lesions appeared as
exophytic lesion or polyps.BB was diagnostic for hamartoma
(n=7),papilloma (n=4),granular cell myoblastoma (n=3),leiomyoma (n=1)
and inflammatory pseudotumor (n=1).In 7 cases, bronchial biopsy removed
the entire tumor.Transthoracic needle biopsy (TNB) was performed in 26
patients and was diagnostic for hamartoma in 13 cases and mixoid tumor
in 1 case.Forty seven patients were treated surgically,most with
lobectomies and segmentectomies.Pathological diagnosis revealed 32
hamartomas,5 solitary fibrous tumors,2 lymphangiomas,2 adenomas,1
chondroma,1 myofibroblastic tumor,1 papilloma,1 inflammatory
pseudotumor,1 granular cell myoblastoma and 1 desmoid tumor.In 18
cases, although diagnostic confirmation, has not been performed
surgical therapy. In 11 cases surgical treatment was refused by the
