Metastases to the breast: great radiological mimicker of primary breast carcinoma and a forgotten entity. A case series of three patients and a review of the literature

Metastases to breast accounts for 0.5-1.3% of all breast malignancies, with the exclusion of leukaemia and lymphoma. These have a wide range of clinical and radiological manifestations and their diagnosis is difficult. There is a need to distinguish them from primary breast carcinoma to prevent unnecessary mastectomy. Imaging and immunohistological correlation plays a vital role in distinguishing this. Our case series review describes the clinical presentation, radiological and histopathological appearances of three patients who presented to our institution.
