ABSTRACT

Glycogen-rich carcinoma of the breast is a rare entity, usually reported with poor prognosis. It has an incidence of between 1.4% to 3% of all breast carcinomas. We present the case of a 48-year-old woman who underwent mastectomy for Glycogen-rich carcinoma of the breast. There was no lymph node metastasis and the tumour was oestrogen receptor (ER) and progesterone receptor positive. The patient was treated with a chemotherapy and an aromatase inhibitor, and has been followed for 48 months with no evidence of recurrence or metastasis.
