Gastric polyps are not created equal: Know your enemy.

Gastric polyps are commonly detected during upper gastrointestinal endoscopy. They are most often benign and rarely become malignant. Nevertheless, adequate knowledge, diagnostic modalities, and management strategies should be the endoscopist's readily available "weapons" to defeat the potentially malignant "enemies". This article sheds light on the valuable effort by Costa to generate a new classification system of gastric polyps as "good", "bad", and "ugly". This comprehensive overview provides clinicians with a simplified decision-making process.
