Esophageal polyp

Esophageal polyp

Esophageal polyps are relatively rare in clinical practice. They are benign tumors with a polypoid appearance originating from the esophageal mucosa or submucosa. They are more common in middle-aged and elderly individuals, with a higher incidence in males than females, typically occurring after the age of 50. The disease course is often long, with slow progression. Symptoms depend on the location and size of the polyp. Larger polyps may present with dysphagia and retrosternal pain, and a few may experience hematemesis and dyspnea. In some cases, long-pedunculated polyps can be regurgitated from the esophageal lumen during severe coughing or vomiting, which is a characteristic symptom of this condition.
