case_images: The patient underwent right mastectomy with axillary sentinel lymph node dissection in September 2015, and the final pathology showed invasive ductal carcinoma, moderately-differentiated (grade 2) (Figure 1(a)), with solid papillary features and necrosis, measuring 3.5 cm in the greatest dimension, with clear surgical margins. It was associated with ductal carcinoma in situ (DCIS) (Figure 1(b)) and lobular carcinoma in situ (LCIS) (Figure 1(c)). One of two right axillary sentinel lymph nodes was positive for micrometastatic carcinoma (Figure 1(d)).
case_images: The peripheral blood showed medium-sized cells that have scanty cytoplasm, fine chromatin, and small nucleoli, resembling lymphoid blasts ((a) and (b), x400).
