[Signet ring cell carcinoma of the Vater's ampulla].

Abstract

We report an unusual type of carcinoma of the ampulla of Vater composed of signet-ring cells with few neuroendocrine cells and without other variants of carcinoma. The tumor presented with obstructive jaundice and invaded diffusely the ampulla and adjacent duodenal wall. The patient is alive and disease free 24 months after Whipple's resection.
