An odd lump in the oesophagus - diagnostic and therapeutic approach?

A 60-year-old woman initially presented with a history of mild haematemesis. The patient denied any dysphagia, weight loss, or fever, intake of non-steroidal anti-inflammatory drugs or excessive alcohol consumption. She did not have abdominal pain and had not observed blood in her stools or melaena. At upper endoscopy, a potential source of bleeding could not be detected, but a subepithelial mass in the mid-oesophagus was revealed. The diagnostic and therapeutic approach to subepithelial oesophageal lesions is discussed.
