Benign obstructing papilloma of the ampulla of Vater in infancy.

Obstructive jaundice due to benign neoplasms of the extrahepatic bile ducts is rare in all age groups. A case is reported which represents the first obstructing papilloma of the ampulla of Vater found in the pediatric age group and the literature pertaining to benign obstructing neoplasms is reviewed briefly. Differential diagnosis of persistent jaundice past the immediate neonatal period is discussed and the need for operative cholangiogram and open liver biopsy in difficult cases is stressed. Obstructing papillomas and other neoplasms of the extrahepatic bile ducts should be added to the differential diagnosis of jaundice in the pediatric age group.
