Computed tomography (CT) scan of the abdomen and pelvis showed irregular wall thickening in the cecum (Figure 1).
(a) Core needle biopsy of the left breast shows an invasive, moderately differentiated infiltrating ductal cell carcinoma with microvascular invasion (H&E, 100x). (b) An invasive, poorly differentiated carcinoma (red arrows) involving the intra-abdominal adipose tissue (black arrow) (H&E, 40x) and (c) the serosal aspect of the appendix (blue arrow = appendiceal mucosa; red arrow = serosal tumor) (H&E, 20x) consistent with breast cancer. (d) Tumor in appendiceal serosa (H&E, 100x).

Histopathologic examination from samples retrieved during the procedure was consistent with an invasive poorly differentiated ER positive carcinoma involving the cecum and appendix (Figures 2(c) and 2(d)) and the intra-abdominal adipose tissue (Figures 2(b) and 3), consistent with a breast cancer as a primary tumor.
