title: [Flat tubulovillous adenoma in the duodenal bulb].
abstract: Yet within the last years adenomas were described in the duodenum, which are frequently found in the colon. The incidence of the lesions in the routine endoscopy of the upper GI-tract was estimated to be 0.23% for tubulo-villous and 0.86% for all adenoma. This case report describes an unusual flat tubulovillous adenoma with cellular atypia covering nearly the whole duodenal bulb which was endoscopically diagnosed.
