Objective:To investigate the clinical and pathological features
diagnosis and prognosis of breast mixed epithelial/mesenchymal metaplastic carcinoma(carcinosarcoma).Methods:The histopathology and immune phenotype of two cases of breast carcinosarcoma in our hospital were observed
studied and discussed
and related literatures were reviewed.Results:Microscopic examination showed that pathological changes were well-demarcated.One case was poorly differentiated invasive ductal carcinoma and chondrosarcoma component;the major component of the other case was malignant fibrous histocytoma
and a few ductal carcinoma in situ were observed on the edge of the lesion.Immunohistochemically
the chondrosarcoma cells of the first case were positive for Vimentin and S-100
negative for CK
the carcinoma cells were positive for CK
negative for ER
PR and C-erbB-2
the sarcoma cells of the second case were positive for Vimentin
CD68 and AACT
negative for CK-pan
P63
CK-low
CK7
CK19
CK5/6 and CK34βE12
the carcinoma cells in situ were positive for CK-pan
negative for ER
PR and C-erbB-2.Conclusion:The primary mixed epithelial/mesenchymal metaplastic carcinoma(carcinosarcoma)in the breast gland was rare
whose diagnosis should be differentiated with the primary sarcoma
malignant phyllodes tumor
carcinoma sarcomatodes
promoting fiber hyperplastic cancer in the breast.
