Abstract
The most common congenital anomaly of the pancreas is pancreatic divisum (Tadokoro et al. in Anat Res Int 2011:1-7, 2011). Agenesis of the dorsal pancreas is extremely rare (Schnedl et al. in World J Gastroenterol 15(3):376-377, 2009). We are reporting a case of agenesis of dorsal pancreas presented with ampullary carcinoma.
