case_images: (a) Right axillary lymph node trucut biopsy; diffuse large B-cell lymphoma. (b) CD 20: Positive in tumor cells. (c) Ki67; 50% proliferation index in tumor cells. (d) Cytokeratin; negative in tumor cells

case_images: Ki67 was 50% (figure 1).
case_images: (a) Right breast trucut biopsy: Invasive breast carcinoma, no special type (ductal), grade II. (b) Her 2: Equivocal: Score 2+ (uniform, intense complete membranous staining in: 5-10% cells). (c) Estrogen receptor; positive, strong staining in 95% of tumor cells. (d) progesterone receptor; positive, strong staining in 50% of tumor cells

case_images: II as shown in figure 2). In contrast, the right axillary lymph node core biopsy showed DLBCL.
case_images: Baseline scan April 2023 (a) axial computed tomography (CT), (b) positron emission tomography only, (c) fused positron emission tomography-CT images through the chest showed fludeoxyglucose (FDG) avid soft tissue mass in the upper outer quadrant of right breast (yellow arrow) has SUV 7.4. FDG avid right axillary lymph nodes (SUV 3.7) are marked with blue arrows, consistent with DLBCL. Small volume mildly avid mediastinal and hilar lymph nodes are likely reactive. (d) Coronal positron emission tomography-only images show hypermetabolic right breast biopsy-proven ductal carcinoma in situ

case_images: PR 50%, and Her-2 neu status was positive on breast biopsy. Positron emission tomography showed fluorodeoxyglucose avid right breast mass and axillary lymph node as can be seen in figure 3.
case_images: Follow-up scan June 2023 (a) axial computed tomography (CT), (b) positron emission tomography only, (c) fused positron emission tomography-CT images through the chest showed significant interval decrease in size and metabolic activity of right breast mgass (yellow arrows) with faint uptake (SUV 2.6). Right axillary lymphadenopathy has also significantly reduced leaving behind residual non-avid (SUV 1.2) subcentimeter nodes (blue arrows). (d) Coronal positron emission tomography-only images showed a faintly avid residual tumor in the right breast
