It is shown in mammary gland molybdenum target as a mass-shape high-density shadow (Figure 1) and shown in ultrasound as a low echo with a size of 2.4 cm x 1.5 cm (Figure 2) at 1-2 o'clock directions of the left breast.

IDC and diffuse proliferation of atypical lymphoid cells were visible (Figure 3), the morphology of lymphocyte with the characteristics of a single form, small to medium size, small round cells, less cytoplasm, smaller nuclear chromatin, less obvious nucleolus and visible mitotic count. Immunohistochemical staining shows IDC was ER, PR and Her-2 negative, while the atypical lymphoid cells were positive for CD20 (Figure 4) and CD23, but negative for CD3, CD5 and CyclinD1.
