Abstract

Context Annular pancreas is an uncommon congenital abnormality. Co-existence of this condition with a pancreaticobiliary malignancy is an exceptionally rare occurrence. Case report We present a case report of a 78- year-old woman with jaundice due to an ampullary carcinoma associated with an annular pancreas treated by pancreaticoduodenectomy. Conclusions A collection of previously reported cases is reviewed together with the relevant literature. Obstructive jaundice is an uncommon feature of annular pancreas; hence the possibility of co-existent pancreaticobiliary malignancy should be excluded. INTRODUCTION Annular pancreas
