Case 1. A 72-year-old man presented with a palpable lump confirmed as invasive ductal carcinoma by excisional biopsy. He reported a family history of breast cancer in his older sister, younger sister, aunt, and cousin. A BRCA gene mutation test was positive. For preoperative work up, mammography, ultrasound (US), and MRI were performed (Fig. 1). The patient underwent bilateral mastectomies. No residual cancer remained in the left breast, but low-grade ductal carcinoma in situ (DCIS) was confirmed in the right breast. Case 2. A 39-year-old man complained of bloody nipple discharge for over 1 year. Diagnostic mammography and US were performed (Fig. 2).
