Its prevalence among gastrointestinal neuroendocrine neoplasms is less than 0.3%, and less than 2% out of periampullary tumours. These neoplasms have relatively poor prognosis. Jaundice and pain in the abdomen are the early and most commonly occurring symptoms with weight loss being a late event. The carcinoid syndrome presents infrequently in periampullary neuroendocrine tumour and happens only if hepatic metastasis occurs. In this scenario, histopathology plays a paramount role in the diagnosis. Specific immunohistochemical staining is used for diagnosis while the treatment options are local excision, endoscopic excision and pancreaticoduodenectomy. Here is a case report of a 42-year-old patient who presented with complaint of obstructive jaundice for one month.
