title: Periampullary mass--a rare presentation of poorly differentiated neuroendocrine cancer of duodenum in a young adult: a case report and review of literature.
abstract: Poorly differentiated neuroendocrine tumour in the periampullary region of the duodenum is a rare entity. This entity usually present in old men. Here we report a periampullary poorly differentiated neuroendocrine cancer (PDEC) of duodenum presenting in a young man with subacute history of jaundice, abdominal pain, pancreatitis and constitutional symptoms. MRI localised the tumour and endoscopy-guided biopsy of the lesion proved the diagnosis. Although palliative surgery and chemotherapy were planned, the patient opted to leave against medical advice.
