Among tumourous affections of the @entity1143 dominate metastatic processes while primary @entity17794 are relatively rare (only 5%). The authors present 4 case-records of less common primary benign @entity5 which were operated at the Surgical Clinic of the Faculty Hospital in Plzen during 2000. Three @entity1 and one @entity1 of different age groups were involved. In three @entity1 accidental findings were involved, in one instance in conjunction with @entity1230 , the fourth @entity1 was examined on account of @entity358 . The diagnosis was based on the skiagram and specially on the CT of the lungs, individually also other methods were used. All findings were radically eliminated--twice by thoracotomy, twice using miniinvasive procedures. Histological examination revealed twice desmoidal @entity81 , once a benign fibrous @entity5 and once a rare variant of @entity12692 . The postoperative period was free from major complications, without the need of surgical revision. Two years after surgery all @entity1 are free from detectable signs of relapse. The authors submit at the same time an integrated view on the problem of @entity5 , they discuss in particular the pitfalls of the diagnosis of these lesions, possible treatment, incl. the use of suitable endoscopic methods, and the prognosis of different types of @entity5 . A more detailed histopathological analysis of the described findings is given.
