title: [A case of primary gastric choriocarcinoma].
abstract: A 66-year-old man with a primary gastric choriocarcinoma is presented. The pre-operative diagnosis of the gastric barium examination and an endoscopy was an unusual gastric carcinoma in the antrum. At laparotomy, an abscess in the lesser sac that had developed by a tumoral penetrance was found. Thus a total gastrectomy and a lymphadenectomy with a reconstruction was performed. The resected specimen was found to be a Borrmann 1 type tumor, and a histological examination showed it to be a choriocarcinoma with a syncytiotrophoblast, that was immunostained by human chorionic gonadotropin (HCG). The physical findings however, disclosed no tumor in the testis. The serum HCG was found to be 1,380 IU/l on the 7th postoperative day, then a pulmonary metastases appeared and progressed, and the patient died on the 22nd postoperative day.
