Abstract

In recent years, the synchronous occurrence of two adjacent but histologically distinct tumors arising in the same organ has been reported. The simultaneous development of gastric adenocarcinoma and gastrointestinal stromal tumor (GIST) is very uncommon. The question raised was whether such a coexistence is a simple incidental finding or whether the two neighboring tumors are caused by a same unknown carcinogenic agent. Many doctors may have an interest in this rare condition and we expect further studies will be done in order to determine if there is any association between the two different tumors. We report a unique case of a synchronous, orthotopic occurrence of an early gastric cancer with GIST in the same location that mimicked advanced gastric cancer.

Key Words: Gastric adenocarcinoma; Gastrointestinal stromal tumors; Synchronous tumor
