An Extragastrointestinal Stromal Tumor Originating from the Pancreas

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract (GIT). In fewer than 5% of cases, GIST originates primarily from outside the GIT. The occurrence of GIST originating from the pancreas is rare. Sometimes, neuroendocrine tumors should be differentiated from GISTs because of their hyperenhancing nature in radiologic images. We report a case of GIST arising in the pancreas that was confirmed by surgical resection.
