Intraductal papillary mucinous neoplasm of the oesophagus: an unusual case of dysphagia

We report the case of a 58-year-old woman presenting with dysphagia secondary to an intraductal papillary mucinous neoplasm arising from a heterotopic pancreas in the oesophageal wall. This was successfully treated with a laparoscopic/thoracoscopic ivor Lewis oesophagectomy. Dysphagia is the most common symptom of oesophageal tumours regardless of aetiology of the tumour and can be treated successfully with surgical resection. Through an extensive search of the literature, we found that a heterotopic pancreas in the oesophagus is extremely rare with only ten cases being reported. We describe what we believe to be the first case of a heterotopic pancreas in the oesophagus transforming into an intraductal papillary mucinous neoplasm.
