Solitary seminal vesicle metastasis from ileal adenocarcinoma presenting with hematospermia: A case report

Figure 1 Positron-emission tomography/computed tomography image revealed a left seminal mass on baseline examination (A) and on contrast (B).

Figure 2 Microscopic view of the tumor in the seminal vesicle: The tumor cells were arranged in trabecular and solid nests, which was compatible with the original small bowel adenocarcinoma. A: HE staining, 100 × magnification; B: HE staining, 400 × magnification.

Figure 3 The tumor cells from the seminal vesicle were positive for CDX-2(++++) (A) and CK20(+) (B). A: CDX2 staining, 400 × magnification; B: CK20 staining, 400 × magnification.
