The most common benign tumour of the oesophagus is leiomyoma. Haemopoietic elements rarely infiltrate oesophageal leiomyoma. We report the case of a 24-year-old man with a long history of intermittent dysphagia. Endoscopy revealed external compression with normal oesophageal mucosa. A barium swallow study showed a defect in the oesophageal wall and a narrow oesophageal lumen. A CT scan of the chest confirmed a mass in the mid-oesophagus. A tumour was excised and the histology report revealed leiomyoma infiltrated with eosinophils, which is a rare variant.
