title: Testicular metastasis from gastric carcinoma: A case report.
abstract: Gastric cancer (GC) is the most prevalent malignancy in the world, especially in China. GC has been postulated to spread via several different routes, including through hematogenous channels, lymphatic vessels, the seeding of peritoneal surfaces, direct extension through the gastric wall, and retrograde extension through the vas deferens or lymphatics. Testicular metastasis is rare. We show here a 53-year-old patient with GC who underwent a radical total gastrectomy approximately 22 mo ago after he presented with a sensation of heaviness and swelling of the right hemiscrotum. The diagnosis of metastatic adenocarcinoma was made after a right-side orchiectomy. We report the first case of testicular metastasis from gastric adenocarcinoma in mainland China and summarize the clinicopathologic features of the disease based on previously published papers.
