Medical imaging presentation of the breast mass. (A) Ultrasound image of a mixed-density multilobulated mass subcutaneous to the breast of an irregular shape and uneven margin; (B) ultrasound image of the pocket of breast prosthesis; (C) MRI image of the breast showing a lobulated mass in the right inner quadrant was adjacent to the margin of the prosthesis, and the vessels were increased and thickened; (D) contrast-enhanced MRI imaging showing that several early enhanced small nodules were seen in the upper posterior area of the tumor and the diffusion was limited, which seems like the satellite lesion of the tumor; (E) enlargement of the image in (D). The capsule of the prosthesis was wrinkled, and the edge of the prosthesis presented the change of chronic inflammation.

The breast ultrasound on August 21, 2020 (Figures 1A,B), showed a lobulated and spiculated hypoechoic solid neoplasm of 28.8*24.5*13.9 mm in the inner lower quadrant of the right breast adjacent to the nipple. August 24, 2020 (Figures 1C-E), confirmed the existence of phyllodes lump and thickening and increase of blood vessels, suspected as a malignant tumor with a grade of 4C of BI-RADS. At the same time, several early enhanced small nodules, which were suspected as the satellite lesions of the tumor, were found in the superior external area of the lump.
Hematoxylin-eosin staining indicated malignant adenomyoepithelioma of the breast lump. (A) Magnification of the main body of the lump (original magnification x40); (B) magnification of the main body of the lump (original magnification x100); (C) magnification of the different areas of the lump body (original magnification x100).

The pathological results are shown in Figures 2, 3.
Hematoxylin-eosin staining revealed that no metastasis was observed in the sentinel lymph nodes of the right breast. (A) Magnification of the main body of the lymph nodes (original magnification x40); (B) magnification of the main body of the lymph nodes (original magnification x100).
