[An autopsy case of gastric metastasis simulating linitis plastica carcinoma from primary linitis plastica carcinoma of the rectum]

Abstract

Cases of a metastatic involvement of the stomach from a colorectal cancer are extremely rare, and once such case, confirmed by autopsy, is reported. The patient, an 86-year-old woman, had a metastatic lesion of the stomach from a rectal cancer. The rectal cancer was a combined linitis plastica type and signet ring cell carcinoma, and the appearance of metastatic lesion of the stomach had simulated the linitis plastica type cancer. A metastatic involvement of the stomach presenting a linitis plastica type cancer from a breast cancer is well documented, but a linitis plastica type from a colorectal cancer has not been reported. This case is the first report concerning a gastric metastasis presenting linitis plastica type lesion from a colorectal cancer.
