Primary gastric chorioadenocarcinoma (PGC) constitutes less than 1% of all gastric cancers; it is more common in men. Approximately one third of patients already have metastatic disease at the time of diagnosis. We present the case of a 70-yearold male patient, diagnosed as gastric adenocarcinoma in anthropylorus, who underwent radical distal gastrectomy. The pathological diagnosis shows an adenocarcinoma, with 85% choriocarcinomatous differentiation, 10% with areas of tubular adenocarcinoma and the remaining 5% per component suggestive of yolk sac tumor. Our patient achieved a survival of 5 months after surgery, during this time he was followed up by oncology medicine with chemotherapy. This disease continues to have a gloomy prognosis; less than 6 months.

Keywords : Choriocarcinoma; Adenocarcinoma; Stomach.
