Synchronous seminal vesicle metastasis from rectosigmoid adenocarcinoma: A case report

Figure 1 Imaging and pathological findings of synchronous seminal vesicle metastasis from rectosigmoid adenocarcinoma. A: Contrast-enhanced computed tomography showing localized narrowing at the rectosigmoid junction, luminal stenosis, and irregular enhancement with diffuse thickening of the colorectal wall; B: Nodular enhancing lesion posterior to the right seminal vesicle; C: Colonoscopy showing an ulcerative circumferential mass with luminal narrowing; D: Moderately differentiated adenocarcinoma invading the subserosal layer. Scale bar: 50 μm; magnification, × 100; E: Cancer cells infiltrating the stromal and muscular layers of the seminal vesicle and forming invasive nests. Scale bar: 200 μm; magnification, × 40.
