Abstract
Introduction: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease affecting young smokers. It is more common betweenthe ages of 20-40 and equals the male/female ratio. Lung biopsy is the most useful methods for diagnosis. The first treatment is to quitsmoking. Corticosteroids or chemotherapeutic agents can be used in severe progressive cases despite of quiting smoking. The patientswith PLCH followed in our clinic were assessed with general clinical features in the light of the literature.Materials and Methods: We retrospectively evaluated patients with PLCH in our clinic between January 1999 and June 2017.Results: The female and male distribution of the 21 patients was 11/10. The average age was 35.04 ± 11.78 years. All patients wereactive smokers at the time of admission. The most common symptom was dyspnea. The most common finding in the pulmonaryfunction tests was obstructive ventilatory defect. The DLCO value of the 70% patient in the carbonmonooxid diffusion test was below80%. The most common pathologic findings detected in high-resolution chest tomography (HRCT) were cystic lesions involvingbilateral upper and middle areas. There were 3 (14%) patients with pneumothorax at the time of admission and 6 (28.5%) patientswith pneumothorax history before. The most common diagnostic method was open lung biopsy. All the patients quit cigarette afterthe diagnosis. There were 6 patients using steroid therapy, 1 patient receiving steroid and bosentan therapy, and 1 patient madepleurectomy due to recurrent pneumothorax. Lung transplantation was done to patient who received combined bosentan treatmentwith steroids.Conclusion: PLCH is a rare disease and should be considered inyoung, smokers with spontaneous pneumothorax and cystic lungdisease in the differential diagnosis. As more diffusions are affectedin patients, respiratory functions for follow-up should be evaluatedwith diffusion tests. It is essential to quit smoking in therapy.
