Abstract
- Gastric carcinosarcoma is an uncommon biphasic malignant tumor. We report the case of 59-year-old man with a history of melena and dizziness. Endoscopic findings showed a fungating mass that originated from the posterior wall of upper body. Radical total gastrectomy with Roux-en-Y esophagojejunostomy was performed. In the resected specimen, immunohistochemical studies for epithelial and mesenchymal markers showed positive reactions. The mass invaded the submucosa without regional lymph node metastasis. Adjuvant chemotherapy with TS-1 (Taiho Pharmaceutical Co. Ltd, Japan) was performed after surgery despite early clinical stage due to aggressive features of carcinosarcoma.
