title: Pedunculated islet-cell tumour of the duodenum.
abstract: An unusual islet-cell tumour found at necropsy in a patient who had died from a myocardial infarction is described. Of particular interest were the pedunculated nature and large size of the tumour. The clinical features of the case are considered. Four islet-cell tumours in the duodenum have previously been reported and it seems probable that such tumours arise in heterotopic pancreas.
