A 62-year-old man with advanced gastric cancer was admitted with a swelling of the left scrotum. He had undergone subtotal and total gastrectomies 10 and 5 years earlier, respectively. A hard mass was palpated along the left spermatic cord associated with hydrocele testis. A left high orhiectomy was performed. Multiple small nodules were noted on the surface of the tunica vaginalis. Also, a tumor in the spermatic cord was present at the level of the internal inguinal ring, protruding into the peritoneal cavity and adherent to the colon. Peritonitis carcinomatosa was recognized. Histopathological diagnosis was tubular adenocarcinoma showing extensive vascular invasion, consistent with a metastasis from gastric cancer.
