Background
Breast metastases from extramammary malignancies are uncommon. However, they are important diagnostic considerations as their treatment and prognosis differ significantly from primary breast cancer. The most common sources are lymphomas/leukemias and melanomas (1). Typical ultrasound (US) features of hematogenous metastases include single or multiple, round to oval shaped, well-circumscribed hypoechoic masses located superficially in subcutaneous tissue or adjacent to the breast parenchyma that is relatively rich in blood supply (1,2, 3). Typical US features of lymphatic breast metastases include diffusely and heterogeneously increased echogenicities in subcutaneous fat and glandular tissue, skin thickening, lymphedema, and lymph node enlargement (1).
