Abstract


 

We aimed to report a case with a gastrointestinal stromal tumor (GIST) of the duodenum that showed only extramural growth, mimicking a pancreatic head tumor.

A 56-year-old woman. Computed tomography revealed a heterogen mass, 12x7x5 cm in diameter, in mid abdominal region preoperatively. Endoscopic examination showed no specific mucosal abnormalities in the duodenal lumen.

A hard mass was detected intraoperatively in the pancreatic head region, and neither peritoneal dissemination nor metastasis was detected. The tumor was diagnosed peroperatively as a GIST in FNA biopsy, and the patient underwent pylorus-preserving pancreaticoduodenectomy because of iatrogenic duodenal injury.

This neoplasm was finally diagnosed histologically as a duodenal GIST with the pancreatic tissue invasion.

This is a rare case of a duodenal GIST with exclusively extramural growth mimicking a pancreatic head tumor.

Key Words: Duodenum, Stromal, Tumor
