【Abstract】 Purpose To study the clinical pathologic characteristics and differential diagnosis of glyogen rich clear cell carcinoma (GRCC) of the breast. Methods Two cases of GRCC of the breast were studied by clinical data, light microscopy and immunohistochemistry.Results One case occurred in a 61 year old male, the another was a 42 year old female. Morphologically, the tumor cells were polygonalorcolumnar with clear cytoplasm and distinct boundary, which were arranged in solid nest, sheet and papillary structures, showing the histologic type of invasive carcinoma with coponent of intraductal carcinoma. Immunohistochemically, the tumor cells were strongly positive for CK(AE1) and CEA, but negative for S 100 protein, actin. Also, the tumor cells were positive for PAS histochemical staining. Conclusions GRCC of the breast is a special type of mammary carcinoma. The diagnosis of the tumor is mainly dependent on histopathology and immunohistochemistry.更多还原
