Esophageal polyps are epithelial tumors of benign esophageal tumors, which are second only to smooth muscle tumors in benign esophageal tumors. Esophageal cancer is a malignant tumor that occurs in the epithelial tissue of the esophagus, accounting for 2% of all malignant tumors.

There is an essential difference between esophageal polyps and esophageal cancer, but experts say that esophageal polyps are very likely to turn into esophageal cancer if they are not treated in time.

Esophageal polyps can occur in any part of the esophagus, but most of them occur in the cervical esophagus, and are most common near the cricopharyngeal muscle. Adenomatous polyps histologically show hyperplasia of the epithelium, basement membrane, basal blood vessels, and connective tissue. Depending on the structure of the underlying tissue, they can be further classified as vesicular adenomas, intratubular cauliflower adenomas, papillary adenomas, and pseudovesicular adenomas. Polyps may protrude into the lumen, may or may not be tipped, and grow relatively slowly. When the tumor is large, it can block the lumen of the esophagus and cause difficulty in swallowing and vomiting. Occasionally, polyps with tips can be spit out through the mouth or blocked in the larynx, causing difficulty in breathing or even choking.

Esophageal polyps, also known as esophageal polyps, are the second most common benign tumors of the esophagus, and their incidence is second only to that of esophageal smooth muscle tumors. Esophageal polyps are slow-growing and the clinical symptoms appear later. The main symptom is dysphagia. Esophageal polyps can ulcerate and bleed, block the lumen of the esophagus or undergo malignant transformation. In individual patients, the esophageal polyps cannot be returned to the esophagus after vomiting into the oral cavity, and suddenly block the pharynx, which can lead to death of the patient by asphyxiation.
