Successful endoscopic resection of an unusually enlarged and pedunculated type I gastric carcinoid tumour.

Three distinct gastric carcinoid (GC) tumour types have been described based on differing biological behaviour and prognoses. Type I GC tumours account for the vast majority (70%-80%), are associated with chronic atrophic gastritis and have a low metastatic potential. Type II carcinoid tumours are the least common (5%-10%), are related to Zollinger-Ellison syndrome and occur in relation to multiple neoplasia type I. Sporadic type III tumours (15%-25%) are the most aggressive type, are unrelated to gastrin over secretion and carry the worst prognosis. In this case report, we present a patient with longstanding gastroesophageal reflux disease (GERD) who presented with epigastric abdominal pain and tarry stools and was found to have a large gastric polyp on endoscopy. Despite current literature recommending surgical resection for larger GC tumours, endoscopic resection was successfully used to excise the tumour with pathology demonstrating complete resection with negative margins.
