Large Lung Consolidation: A Rare Presentation of Pulmonary Sarcoidosis.

Sarcoidosis is a complex inflammatory disease of uncertain origin, characterized by non-necrotizing epithelioid cell granulomas (NNEGs) affecting multiple organ systems. Although many different clinical and pathological phenotypes can be present, with different organs involved, the lung is the most common site described. In this case report, we (a) present and discuss the broad differential diagnosis of a patient presenting with a solitary lung mass with clinical and imaging features of lung cancer that ultimately was confirmed with a rare manifestation of stage II pulmonary sarcoidosis, and (b) analyze and compare similar cases from the literature.
