Background: Diffuse pulmonary ossification is a rare abnormal finding characterized by the formation of mature bone tissue both in the interstitium and in the cells, with or without evidence of bone marrow. May be idiopathic or associated with chronic pulmonary, cardiac or systemic diseases. Men are affected more often than the women, usually between the sixth and eighth decade of life. They described two histologic types of pulmonary ossification: the perigraptos nodular (nodular) type and 2) dendritic (dendriform) guy. The purpose of this paper is to present an event with diffuse pulmonary ossification in a better understanding of the entity and membership in the differential diagnosis of interstitial lung disease.

Patients and methods: This man, 68 year old former smoker with a history of coronary heart disease, hypertension, chronic bronchitis, which was referred to the Cardiac Clinic G.N.TH. “C. Smear “because persistent pneumothorax. Under investigation, computed tomography (CT) chest revealed multiple bilateral cysts sizeable gaseous, multiple nodules in the lower lobes ypoupezokotika lung and presence of pneumothorax in the left hemithorax. Mini left thoracotomy was performed and received bioptic material.

Results: Histological examination showed lung parenchyma with the presence of multiple cystic formations with fibrin in the wall and a reduction of the pulmonary parenchyma. In several places there ossified tissue with presence myelochoron and bone marrow cells in afton. I diagnosis was entered: lung parenchyma with the presence emfysimatikon cysts and foci of ossification.

Conclusions: Diffuse pulmonary ossification remains underdiagnosed during life. Most cases are an incidental finding at autopsy, and that the absence of symptoms. An early diagnosis will allow for better treatment of the natural course of the disease, while paving the way for new therapeutic strategies.
