[Nodular lymphoid hyperplasia of the duodenum in cancers of the gastrointestinal tract].

In an autoptic study the coincidence of carcinomas of the gastrointestinal tract and nodular lymphoid hyperplasia (NLH) of the duodenum was studied histologically. Out of sixty cases of carcinomas in the gastrointestinal tract not one case of concomitant NLH in the duodenum could be demonstrated, nor in the first section of the jejunum, which was examined for comparison's sake. A connection between NLH and carcinomas of the gastrointestinal tract, as pointed out in the literature, could not be confirmed through this study.
