Abstract:
Glycogen-rich clear cell carcinoma of the breast is very rare(l -3% of breast cancer). It is defined as a tumor composed of more than 50% of optically clear, neoplastic cells, characterized by centrally located nuclei and abundant cytoplasm, being positive for periodic acid Schiff(PAS) and negative for periodic acid Schiff after diastase(D-PAS) treatment. In the absence of intraductal or in situ lobular carcinoma component, metastatic clear cell carcinomas of other organs should be considered as diagnostic possibilities. We report a case of glycogen-rich clear cell carcinoma arisen in a 62-year-old woman. The tumor revealed both solid and papillary pattern with intraductal component. The neoplastic cells had clear cytoplasm, which were PAS positive, D-PAS negative, mucicarmine negative and oil red 0 negative. More than 90% of tumor cells exhibited moderate staining for anti-estrogen receptor monoclonal antibody. Flow cytometric DNA analysis revealed diploid DNA content.
