[Clinicopathological study of a malignant lesion in the remnant stomach].

Thirty-six cases of malignant lesion in the remnant stomach were studied clinicopathologically. Ten had been surgically managed as benign lesions and eight were suspected of being metachronous multiple gastric cancer. The pathological characteristics of the malignant lesions and the operation interval (mostly more than 10 years) were similar in these two groups. Although malignant lesion in the remnant stomach is difficult to differentiate clearly when there is no sufficient histological evidence, the operation interval of more than 10 years can be one of the criteria for differential diagnosis.
