Insidious Onset of Pulmonary Langerhans Cell Histiocytosis During Oncological Follow-Up

Abstract

Teaching Point: Pulmonary Langerhans cell histiocytosis (PLCH) has to be included in the differential diagnosis of cystic pulmonary lesions on chest computed tomography (CT). CT has important diagnostic value by demonstrating initial centrilobular nodules that in time cavitate and transform into cysts, typically sparing the costophrenic angles.
