[Case of a sigmoid colon cancer with metachronous metastases of the stomach and the abdominal wall].
We report a rare case of a 73-year-old man with gastric metastasis from colorectal cancer. Tumors of the stomach and the right side abdominal wall were diagnosed by FDG/PET-CT. Upper gastrointestinal endoscopy revealed a submucosal tumor with central depression in the fornix of the stomach. Since sigmoidectomy had been performed for cancer 39 months ago, we suspected metastasis. Proximal gastrectomy and resection of the tumor of the abdominal wall were performed. Histological findings showed moderately differentiated adenocarcinoma in the submucosal tumor. Immunohistochemical studies revealed focal positive staining for CK20 and diffuse for CDX2. These findings were similar to those of his primary sigmoid colon cancer and therefore metastasis was diagnosed.
