Abstract

Alpha-fetoprotein producing gastric cancer accounts for less than 10% of the gastric adenocarcinomas. Different histologic subtypes may exist, the least common of which is yolk sac morphology. To the best of our knowledge less than 10 cases have been reported with high alpha-fetoprotein and yolk sac components, either pure or mixed with ordinary adenocarcinoma of the stomach. During 10 years, from among more than 500 gastric adenocarcinoma cases that presented to the largest referral center in Southern Iran, two cases of gastric cancer with yolk sac components and high alphafetoprotein have been diagnosed, as presented in this case report.
