Metastatic breast cancer masquerading as a renal malignancy: A literature review and case report

Breast cancer is the most common non-cutaneous cancer affecting women. Despite this high incidence, few cases of non-disseminated breast cancer metastasizing to the kidneys have been reported. This report documents a 78-year-old female in remission for twelve years following lobular breast cancer treatment who presents with haematuria associated with a right renal pelvis lesion. Histological analysis revealed this lesion was metastatic lobular breast carcinoma. A systematic review yielded 15 documented cases of non-disseminated breast cancer metastasizing to the kidneys. This systematic review represents that most comprehensive review of the clinical presentation, pathology, prognosis and management of this rare presentation.
