A 70-year-old woman presented with an enlarging mass in the upper outer quadrant of the right breast. Digital mammography revealed a microlobulated mass in the right breast (Fig. 1a). A breast ultrasound examination was performed using an ACUSON Sequoia with an 18L6 transducer (Siemens Healthineers, Tokyo, Japan). On B-mode ultrasound examination, the tumor was lobulated with rough and well-defined margins. Heterogeneous internal echoes with highly accentuated posterior echoes and bilateral shadows were observed (Fig. 1b). Enhanced magnetic resonance imaging findings showed a clearly demarcated mass containing cystic lesions (Fig. 1c).

a No calcifications were noted in the mass on digital mammography. b The mass had a size of 28 × 25 × 20 mm. c Magnetic resonance imaging revealed a 33 × 32 × 22-mm irregular mass on the upper right lateral side. d Loupe image, hematoxylin and eosin staining. Part of the tumor was necrotic, and the central part of cartilage metaplasia had cavities due to liquefaction. e Metaplastic cartilage tissue. f The tumor cells were dense in this area. g The site of the necrotic material is presented
