BACKGROUND: @entity189 ( @entity189 ) is a rare @entity5 with @entity5 and sarcomatoid tissues. The aim of this study is to investigate the clinical manifestations and pathological findings of @entity189 of the lung. METHODS: Data including clinical manifestations, pathological findings, treatment were retrospectively analysed from fourteen @entity1 with @entity2 confirmed by pathology and follow-up was carried out. RESULTS: Mean age at onset was 62 years old and gender ratios (M/F) in these @entity1 was 6:1. The clinical manifestations of @entity2 were similar to that of other types of @entity2 while there were characteristic findings on the enhancement CT scan. Bronchofiberscopy was not a reliable examination for final diagnosis. Cells with endothelial phenotype could be detected by immunohistochemical method. CONCLUSIONS: The final diagnosis of this disease depends on histopathological observation, while the diagnosis may be missed among @entity1 without surgical intervention. Immunohistochemical examination is helpful for diagnosis and differential diagnosis. The therapeutic strategy is coincident with that for @entity1149 .
