astrointestinal stromal tumors (GIST) are solid of the gastrointestinal tract. The stomach is most common site while esophagus least for tumors. cystic Gastrointestinal tumor has never been reported in past. On CT scan a young male patient, we an exophytic structure 2.5 x 2.2 cm along as esophageal duplication cyst then he underwent image-guided biopsy that finally turned out to be on histopath...
Gastrointestinal stromal tumors have a wide spectrum of biologic behavior, and occasional cases show liver metastases. The modified risk grade based on tumor size and mitotic counts has been proposed to predict the biologic behavior in gastric gastrointestinal stromal tumors. Blood vessel invasion (BVI) is important in the development of metastasis of various kinds of cancer. The aim of this st...
AIMS AND BACKGROUND In patients with localized gastrointestinal stromal tumors, surgery remains the elective treatment. Nowadays, imatinib therapy has been standardized in advanced gastrointestinal stromal tumors, showing continuous improvements in progression-free and overall survival. A combination of imatinib therapy and surgery may also be effective in a subset of patients with metastatic o...
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...
INTRODUCTION Gastrointestinal stromal tumors are the commonest mesenchymal tumors of the gastrointestinal tract, the stomach and small intestine are the favored sites of occurrence. They rarely occur in the colon, rectum and esophagus. GIST is neoplasm of mesenchymal origin originating from precursors of the interstitial cells of cajal. The symptoms of gastrointestinal stromal tumor depend on t...
INTRODUCTION Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. These tumors represent more than 80% of all mesenchymal tumors found in the gastrointestinal tract, though they account for only approximately 3% of all gastrointestinal malignancies. Literature offers case reports, which describe symptomatic gastrointestinal stromal tumors and ...
INTRODUCTION Gastrointestinal stromal tumors are rare tumors. They commonly metastasize within the abdominal cavity, particularly to the liver. Less commonly, metastases can be found in the bone. CASE PRESENTATION We here present a case of metastasis to the scapula in a 54-year-old Caucasian male patient with an advanced gastrointestinal stromal tumor, which was subsequently successfully trea...
