[Primary manifestation of monophasic synovial sarcoma in the lung]

The authors introduce a case of a 41 years old male patient who was examined first on pulmonology department due to thoracic pain, haemoptoe and fever. In the background of symptoms a 10 cms diameter formation was found in the right thorax side joined to the hilus. Even a through row of examination was unable to determine the histologic type. After the patient's admittance to the authors' thoracic surgery department the tumor occupying the central part of the right upper pulmonary lobe was resected by lobectomy via right thoracotomy. The histologic result was monophasic synovial sarcoma of which primary pulmonary appearance is very rare. The authors consider the rarity of this tumor type worth to publish.
