title: Metaplastic breast cancer.
abstract: Metaplastic breast carcinoma is uncommon and constitutes less than 5% of all breast cancers. The cancerous epithelium becomes non-glandular through metaplastic differentiation. There are various subtypes and the extent to which this process occurs varies. A case of a 52-year-old female patient is reported and the published literature is reviewed.
