title: [Malignant transformation of multiple gastric adenomatous polyps in a teenage girl: a case report].
abstract: A 14-year-old female was found to have gastric polyposis by gastroscopy and barium meal study. During operation, multiple polyps in different sizes were noted over the whole stomach, the largest one measured 6 x 6 x 4 cm. The pathological report was adenomatous polyps. After 4 years, the polyps finally transformed to multifocal gastric adenocarcinoma. The relationship between gastric polyps and gastric adenocarcinoma, and the management of gastric polyposis were discussed.
