  • Abstract
  • Look Inside

 A 75-year-old man was admitted to our hospital for a gastric tumor. He had no symptom and physical examination was unremarkable. Laboratory findings were normal except for positive fecal occult blood. An upper gastrointestinal series demonstrated a large intragastric tumor involving the gastric body extending into the antrum, which showed a“soap-bubble”appearance. Endscopic findings showed a large sessile, flatly elevated tumor which occupied the entire circumference of the lumen. Although multiple biopsies revealed tubulovilkrus adenoma, total gastrectomy was performed because of the possibility of focal cancer.

 Grossly, the tumor measuring 19×11×0.7 cm was a broad-based, flatly protruded lesion with villous and fine granular surface. Microscopically, the lesion consisted of a proliferation of adenomatous epithelium growing in a striking villous pattern, partly composed of well differentiated adenocarcinoma.
