Aim: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal neoplasia of gastrointestinal system. Radical surgery with negative margin is important step for treatment GIST. The primary aim this study was to evaluate risk factors recurrence in patients who underwent diagnosis Secondary reveal that affect survival. Materials and Methods: data 28 GIST our clinic between January 201...

We report the case of a 64-year-old woman with a gastrointestinal stromal tumor and a diffuse large cell lymphoma. For this case, we conducted a literature review in an attempt to correlate these two neoplasms on a molecular basis. Diffuse large cell lymphoma is a subtype of non-Hodgkin lymphomas. The etiologic factor of these lymphomas is considered to be the mutations or allelic losses of the...

Mounting evidence demonstrates the presence of extragastrointestinal stromal tumor (EGIST) which originates from tissues outside the gastrointestinal (GI) tract and shares overlapping immunohistological features with gastrointestinal stromal tumor (GIST). GIST emanating from prostate is extremely rare. To our knowledge, there are only 3 definitely reported cases of primary prostatic EGIST. Here...

Gastrointestinal stromal tumors (GISTs) originate from interstitial Cajal cells on intestinal pacemaker cells that arise from the muscularis propria of the gastrointestinal tract wall. GISTs are characterized by the expression of c-KIT protein (CD 117, stem cell factor receptor) and are the most common mesenchymal tumors of the digestive tract. That protein, which is detected via immunohistoche...

BACKGROUND The location of gastrointestinal stromal tumors (GIST) outside of the gastrointestinal system is a rare event. CASE PRESENTATION A 56-year old woman presented with a GIST of the pelvis was misdiagnosed and treated as a uterine leiomyosarcoma. The diagnosis was made after the CD117 (KIT) positivity in the biopsy of the excised bowel mass four years from the first presentation. Durin...

Introduction: Gastrointestinal stromal tumors constitute a distinct group of rare gastrointestinal tract tumors that originate from the interstitial cells of Cajal. These jejunoileal lesions are a rare cause of obstruction but can be associated with substantial morbidity. Case: A 59-year-old woman presented to the emergency department with abdominal pain and distention. Physical examination rev...
