摘要
Primary clear cell carcinoma of the breast is a rare tumor with different morphological characteristics compared to ordinary breast carcinomas. The clear cell morphology of the neoplastic population in these tumors has been ascribed to the presence of intracellular lipid, mucin or glycogen, or to myoepithelaial, apocrine, or neuroendocrine differentiation. We describe 2 cases of glycogen-rich clear cell carcinoma of the breast as follows.
