A Case Report, Well Differentiated Adenocarcinoma Change from Gastric Hyperplastic Polyp during 7 Years Follow up

Abstract

A 56-year-old female was hospitalized with multiple gastric polyps pointed out at the complete physical examination in August 1989. By the gastroscope, multiple polyps were observed from lower body to fornix of the stomach. They were completely diagnosed hyperplastic polyps by the biopsy specimens. After that, every year, gastroscopy and the biopsy was performed.
In March 1996, we find a view of structural atypical change of the mucosal glands form the specimens taken from the biggest polyp. February 1997, the polyp was suspected to be partially changed adenocarcinoma, we proceeded endoscopic mucosal resection. The clubbing from polyp was measured 52×15mm. Histological examination showed 52×15mm, well differentiated adenocarcinoma.
We observed a case of well differentiated adenocarcinoma change from gastric hyperplastic polyp during 7 years.
