Abstract
- Most tumors affecting Vater's ampulla are adenocarcinomas, but a neuroendocrine carcinoma in the ampulla of Vater is extremely rare. The coexistence of these two tumors has been reported in only a few cases. Here, we report a rare case of a collision tumor of the ampulla of Vater with an adenocarcinoma and a large cell neuroendocrine carcinoma.
