An Uncommon Cause of Bilateral Pulmonary Nodules in a Long-Term Smoker

Abstract

Pulmonary Langerhans Cell Histiocytosis (LCH) in adults is a rare disease and no precise epidemiological data are available concerning its prevalence. Bilateral diffuse nodular infiltration without cystic changes could be one of the Langerhans Cell Histiocytosis (LCH) presentation depend on the stage of evolution of the process. We are reporting in this case an early possible manifestation of LCH that can mimic other wide deferential diagnosis especially among smokers.
