Abstract

Cryptogenic organizing pneumonia, a unique clinicopathologic entity, is a current and many faceted issue due to its terminological equivalents and differential diagnostic features according to various clinics. Our first case with organizing pneumonia was diagnosed via transbronchial lung biopsy, performed for bilateral pulmonary consolidations unresolved by antibiotic treatment. The second case, who had a left lower lobe mass, was diagnosed by thoracotomy carried out due to a preliminary diagnosis of malignancy. Both cases were considered as “Cryptogenic” organizing pneumonia since no underlying factors could be related and a long term follow-up was achieved. We aimed to review the current literature together with a presention of the clinical, radiological and histopathological findings of our two cases.
