Invasive papillary carcinoma (IPC) and glycogen-rich clear cell carcinoma (GRCCC) are rare primary breast carcinomas. IPC typically have favorable prognosis, whereas the prognosis of GRCCC is less established. We report a unique case of high-grade invasive mammary carcinoma with mixed IPC and GRCCC features. We review the imaging and pathologic features and discuss prognosis of these unusual breast cancer subtypes.
