Pulmoner Langerhans Hücreli Histiositozis X: Dört Olgunun Analizi* Pulmonary Langerhans Cell Histiocytosis X: An Analysis of Four Cases

Pulmonary Langerhans Cell Histiocytosis (PLCH) X, which is a subgroup of Langerhans Cell Histioycytosis, is an idiopathic interstitial lung disease in which Langerhans cell infiltration is seen in the lung. PLCH X has a wide spectrum of symptoms from nonproductive cough and dyspnea to spontaneous pneumothorax, and more than 90 % patients who have these diseases are smokers. Reticular and cystic patterns were observed on the upper and middle lung lobes at high resolution computed tomography. PLCH X is a rare disease, and should be considered in patients who are younger, smokers, and patients who apply to the hospital by presenting with spontaneous pneumothorax. To contribute to the literature, four cases, which were followed, are presented, as it is a rare disease.
