Our purpose in writing this paper is to record our experiences and difficulties, and the results of treatments, in cases of carcinoma of the duodenum, rather than to describe all aspects of the disease. For this reason, we have not thought it necessary to repeat much of the ground so thoroughly covered by the many authors writing on the subject. A detailed bibliography was therefore deleted from this paper.

Of the various locations, the infrapapillary type is the least frequent. In 453 proved cases of carcinoma of the duodenum reported by Kleinerman,1 22.5% were suprapapillary, 59.2% were peripapillary, and 18.3% were infrapapillary. The two cases herein reported were both of the infrapapillary variety.
