Introduction: Ectopic liver (EL) is a rare entity, which is reported to develop at various sites, such as the abdominal cavity, the retroperitoneal cavity, the pleural cavity, and the mediastinum.
Patient concerns: A 27-year-old previously healthy Chinese man suffered from a discontinuous abdominal pain in the upper abdomen for 2 months.
Diagnosis: The upper gastrointestinal endoscopy revealed there was a polypoid mucosal uplift on the distal region of the esophagus near the cardia.
Interventions: Endoscopic polypectomy was performed.
Outcomes: Pathology examination showed the liver tissue.
Conclusion: EL should be excised as it may possibly lead to the development of a malignancy. Endoscopic resection was found to be safe and reliable in this case.
