Abstract

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract. Oesophageal GISTs are extremely uncommon, accounting for 0.7% of all GISTs, and their management is surrounded by some debate. We report a case of a 70-year-old man who was incidentally diagnosed with an oesophageal lesion on a 18F-fluorodeoxyglucose positron emission tomography. An endoscopic study revealed a non-obstructing 40 mm oesophageal lesion. Endoscopic ultrasound showed a well-circumscribed submucosal tumour on the middle oesophagus. Fine-needle aspiration was positive for CD117 and the overall features were of a GIST. After an initial thoracoscopic approach, the tumour was completely enucleated through a thoracotomy incision. The patient experienced no surgical complications and was discharged on day 4. Histopathology and immunohistochemical staining confirmed a low-risk GIST.

Keywords: cancer intervention; cardiothoracic surgery; general surgery; oesophageal cancer; surgical oncology.
