simultaneous a collision tumor of stomach consisting of adenocarcinoma and gastrointestinal stromal tumor (gist) is very rare based on our knowledge. this coexistence has rarely been reported in literatures. we report a case of 64-year-old woman who has diagnosed with prepyloric poorly-differentiated diffuse signet-ring cell type adenocarcinoma and has undergone an elective d2 total gastrectomy...

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that most commonly affect the stomach or small intestine, but can occur anywhere throughout the gastrointestinal tract. To the best of our knowledge, few cases have been reported in the literature about the femur metastasis of GIST. This paper describes a metastasis of a gastrointestinal stromal tumour (GIST) to the femur in a 62...

Gastrointestinal stromal tumor (GIST) is a rare form of mesenchymal tumor of the gastrointestinal tract, accounting for 1% of malignant neoplasms [1]. Most gastrointestinal mesenchymal tumors are GISTs, originating from interstitial cells of Cajal or precursors of these cells. Although several reports regarding GIST have incrementally advanced our understanding of this condition in recent years...

Retroperitoneal E-GIST is a very rare tumor and a total of 58 cases have been reported in the literature (2). The distinction of E-GIST from gastrointestinal stromal tumors (GIST) is made by proving the origin outside the alimentary system and ruling out a concurrent neoplasm in the gastrointestinal tract. In this letter, we aimed to report a very rare form of E-GIST arising from the retroperit...

Received October 2009 Accepted November 2009 INTRODUCTION A gastrointestinal stromal tumor (GIST) is primarily located in the gastrointestinal tract. It is classified as a mesenchymal tumor that shows a CD117 (c-KIT)-positive mesenchymal spindle or epithelioid neoplasm. Tumors outside the gastrointestinal tract that were histologically similar to GISTs and showed immunopositivity for CD117 were...
