Computed tomography (CT) image revealed right lobe of liver, seminal vesicle, and space between the spleen and stomach masses. (A) and (B), right lobe of liver mass (short white arrow) and space between the spleen and stomach mass (short black arrow) at baseline examination and portal phase of CT image; (C) and (D), left seminal vesicle (long black arrow) at baseline examination and portal phase of CT image. CT = computed tomography.

On 20 March 2015, the CT image showed masses in right lobe of liver, seminal vesicle and space occupying mass between the spleen and stomach (Fig. 1).
Endoscopic ultrasound-guided-fine-needle aspiration (EUS-FNA) image showed masses in liver and seminal vesicle. (A) and (B), porta hepatis image with EUS-FNA; (C) and (D), seminal vesicle image with EUS-FNA. EUS-FNA = endoscopic ultrasound-guided-fine-needle aspiration.

We performed endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for liver and seminal vesicle lesions (Fig. 2) and postoperative pathology revealed malignancy.
The pathology and immunohistochemical analysis with seminal vesicle mass. (A) and (B), a microscopic view of the tumor in the seminal vesicle; (C), the tumor cells from the seminal vesicle were positive for GPC3; (D), the tumor cells from the seminal vesicle were positive for HEPT1.
