[A case of primary gastric choriocarcinoma].
Primary gastric choriocarcinoma is an extremely rare and poor prognosis. A 73-year-old man who had appetite loss was admitted to our hospital in May 2006. Abdominal CT showed tumor measured 9x7 cm in size between residual stomach and pancreas. Gastrointestinal endoscopy revealed that gastric posterior wall was compressed and soft necrotic elevated tissue with coagulation. Endoscopic biopsy specimens showed poorly differentiated adenocarcinoma. Total gastrectomy with D2 lymphadenectomy, distal pancreatectomy, splenectomy, and partial resection of transverse colon were performed. Histological findings of resected specimens showed choriocarcinoma which demonstrated reactivity against anti-hCG antibody by immunohistochemical staining. Forty five days after the operation, skin metastasis appeared, and he died of this disease 60 days after the operation.
