[Benign tumors of the lungs and bronchi].
Results of a retrospective study from the years 1961 to 1986 have been presented based on hospitalization of 292 patients with benign tumours of the lungs and bronchi verified by histology. The prevailing tumours in the cohort were chondrohamartomas (62.0%) and carcinoids (21.9%). The tumours were localized more frequently inside the parenchyma (75.7%) than inside the bronchi (24.3%). The patients were men in 59.9% and women in 40.1%, the mean age during hospitalization being 48.8 years. In 60.6% of the patients the tumours were detected during an accidental radiographic examination, the tumour increased in size over several years of observation in 22.6% of the patients. A total of 280 patients (95.5%) were surgically treated, the tumour was removed in the bronchoscopic way in nine cases, two patients could not be operated on for advanced processes and one patient refused the operation. In 83.2% of the patients the surgical intervention was smaller than lobectomy, larger interventions prevailed in endobronchial localization making 54% on the whole, bronchial carcinoids being 71% of these.
