Local resection of gastrointestinal stromal tumor of the second part of duodenum.

Gastrointestinal stromal tumors are relatively rare in the duodenum, representing 2-4% of Gastrointestinal stromal tumors of the gastrointestinal tract. We describe a huge Gastrointestinal stromal tumor arising from the second part of the duodenum invading the transverse colon which was removed successfully by local resection of the second part of the duodenum along with a segment of transverse colon.
