Abstract
Langerhans cell histiocytosis is a clonal neoplastic process characterized by cell proliferation of the Langerhans type, with the expression of CD1a, CD207 and S100 proteins and the presence of Birbek granules. We present a case of a 31-year-old woman with a verified osteosarcoma of the proximal epimetaphysis of the left tibia. Also she has multiple thin-walled cysts and foci in the lungs. The case is interesting for the rare combination of osteosarcoma of the bone and pulmonary histiocytosis. This case show that foci in lungs can simulates metastatic disease according to computed tomography (CT). Multidisciplinary approach of pathologist, oncologist and radiologist help revealed diagnose.Keywords
