Abstract [eng] Gastric polyps are lesions which arise from different cells or epithelial tissue in the stomach and with different causes, histology, malignant potential, and association with different tumor predisposition syndromes. These lesions are usually benign but because they represent proliferative growth they can contain the potential for malignant transformation. Gastric polyps have many subsets, the most commonly seen and described are the triad of gastric hyperplastic polyps characterized by pronounced foveolar hyperplasia, fundic gland polyps, characterized by dilated and irregularly budded fundic glands predominantly lined by parietal cells with smaller proportion of chief cells, and adenomatous polyps characterized by low-grade glandular dysplasia. Gastric polyps are usually found incidentally on upper gastrointestinal endoscopy performed for an unrelated indication and only in rare cases do they cause the symptoms. Nevertheless, the diagnosis and appropriate management of gastric polyps are important, as some polyps have malignant potential.
