Abstract
Introduction: Lung pathologies, which are called Local Organizing Pneumonia and Local Bronchiolitis obliterans with organizing pneumonia (BOOP) in the literatüre, cannot be precisely diagnosed can undergo operation. These have become increasingly common in benign lung pathologies. Studies have rarely detected them and very few articles mention small case series.
Materials and Methods: Between January 2013 and December 2017, a total of 2595 patients underwent resection in our clinic due to a lung mass. Of these patients, 407 underwent wedge resection while 2151 anatomical resection. A total of 52 patients with final pathology reported as local organizing pneumonia(LOP) were evaluated. All patients were preoperatively evaluated with medical history, physical examination, age, gender, smoking, thoraxCT, PET-CT, bronchoscopy and PFT.
Findings: The patients with final pathology reported as LOP underwent wedge with videothoracoscopic or thoracotomy(n=28,%54) resection and lobectomy(n=24,%46). The most common symptom in the patients was coughing(n=50%). 94%(n=49) of the patients had a history of smoking over 10packs/year. Chronic obstructive pulmonary disease was the most common concomitant disease(n=39%). SUV involvement of the mass ranged from 2.8 to 11.7. The mean lesion size was 4.1(2.8 to 7.3). The mean follow-up period was 49 months.
Discussion: Because of the presence of organizing pneumonia adjacent to malignant neoplasms, solitary nodules should always be considered carefully. Surgery should not be avoided in patients in whom the disease cannot be diagnosed, does not regress in follow-up, who have a history of smoking, hemoptysis and radiologically suspected malignancy.
