Abstract |
|
Gastointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. They are frequently identified as incidental lesions found by routine endoscopy or in resection specimens that are removed for other reasons. The macroscopic morphology of GISTs may be classified as the intraluminal type, extraluminal type, mixed type and intramural type. The extraluminal type is the second most frequent tumor encountered, but a GIST pedunculated externally from the stomach is very rare. In addition, the myxoid epithelioid variant, which is characterized by an unusually myxoid stroma and epithelioid histology, is also a rare distinct subtype of a GIST that is closely correlated with negative immunoreactivity for c-kit. We report a case of a myxoid epithelioid variant of a pedunculated extraluminal GIST in a 62-year-old man that presented with an abdominal mass. (Korean J Gastrointest Endosc 2008;37:349-354) |
