Synchronous Jejunal Gastrointestinal Stromal Tumor and Primary Adenocarcinoma of the Colon

摘要

Synchronous gastrointestinal stromal tumors (GIST) and primary epithelial cancers of the gastrointestinal tract is an uncommon occurrence. We report a case of jejunal GIST which was detected incidentally in a patient during surgery for carcinoma of the sigmoid colon. The uncommon association of such synchronous tumors prompts a search for a common molecular pathway for carcinogenesis in gastrointestinal epithelial and stromal tumors.
