  • Title: [Hyperplastic polyp with neoplastic transformation in a patient with atrophic gastritis and multiple gastric neuroendocrine tumors].
    Author: Moura EG, Domingos TA, Alvarado H, Iriya K, Kishi HS, Martins BC, Moura ET, P PS.
    Journal: Rev Gastroenterol Mex; 2012; 77(2):96-8. PubMed ID: 22658549.
    Abstract:
    Hyperplastic gastric polyps are often found at GI endoscopy and are not considered premalignant lesions, although some cases of malignancy have been reported. Neuroendocrine tumors, conversely, are rare and account for approximately 1% to 2% of gastric polyps. Both hyperplastic gastric polyps and neuroendocrine tumors are related to gastric atrophy. The case of a hyperplastic polyp with multifocal areas of adenocarcinoma within the polyp associated to multiple gastric neuroendocrine tumors is reported.
