Gastric cancer with adenocarcinoma and yolk sac tumor components: A rare entity.

Despite a sharp worldwide decline in the incidence and mortality due to gastric cancer during the second half of the 20th century, gastric cancer remains the world's second leading cause of cancer-related deaths. Variants of gastric cancer account for approximately 5% of all stomach carcinomas. Herein, we report on a rare case of combined germ cell tumor and adenocarcinoma that arose in the stomach of a 68-year-old woman with a high level of alpha-fetoprotein in the serum. Clinical and pathological findings are presented.
