Diagnosis and Differential Diagnosis of Sclerosing Hemangioma of the Lung

Objective To investigate the diagnosis and differential diagnosis of sclerosing hemangioma of the lung(SHL).Method Detailed pathologic observations were conducted on 8 cases of SHL,with particular attention upon theirsecondary pathological changes.Results SHL usually occured in female patientsof middle or young ages,and mostly located at the peripheral region of middle or right lobes.Under microscope,the basic pathological changes were irregularly distributed clefts and papillary structures in parenchyma areas of tumor cells.Secondary changes were usually presented,such as hemorrhage,chronic inflammatory cells infiltration,foamy cells accumulation,hyaline change of small blood vessels and fibrosis.Misdiagnosis was easily made because of these secondary changes.Conclusion Discovery of parenchyma areas of tumor cells was the key point of SHL diagnosis when secondary pathological changes were marked.
