ABSTRACT

Multiple primary tumors are defined as cases involving primary malignant tumors of different histologic origins in one person. Recently, the number of reports dealing with multiple primary tumors has been increasing due to more developed diagnostic procedures and patients with longer survival rates. Both the occurrence of multiple primary tumors and the primary adenocarcinoma of the duodenum are infrequent, accounting for less than 1% of all carcinoma of the gastrointestinal tract. Also, It has been reported that duodenal bulb cancer combined with early gastric cancer is extremely rare. One case was experienced involving duodenal bulb cancer combined with early gastric carcinoma, and is herein reported with a review of related literatures.
