Extra-Gastrointestinal Stromal Tumor of the Omentum: A Rare Case Report and Review of the Literature

Abstract: Gastrointestinal stromal tumors (GIST) are uncommon mesenchymal spindle-cell or epithelioid neoplasms, located mainly with higher frequency in the stomach and small bowel. GISTs represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein a transmembrane tyrosine kinase receptor for stem cell factor. Extra-gastrointestinal stromal tumors tend to present In fewer than 5% of cases; they originate primarily from the mesentery, omentum or peritoneum.… Show more

“…A small subgroup of GIST originates from outside the gastrointestinal tract and is referred to as extragastrointestinal stromal tumors (EGIST). EGISTs display no connection to the walls or serosal surfaces of GI tubular organ and account for 5%-10% of all GISTs [1]. Approximately 80% are located in extragastrointestinal abdominal wall structures including omentum or mesentery; retroperitoneum, abdominal wall, liver and pancreas represent rare sites of occurrence.…”

“…EGISTs display morphological and phenotypic similarities with GISTs and are thought to develop from the detachment of a primary intra-abdominal tumor or from independent mesenchymal cell growth of the mesentery, omentum and retroperitoneum [1,5].…”

“…These tumours are found most often in the stomach, jejunum and ileum and far less commonly in the duodenum, rectum, colon and oesophagus 2 3. Extra-GISTs (EGISTs) occur in less than 5% of cases, and can arise from the mesentery, retroperitoneum, peritoneum or omentum.…”

“…Although still the subject of ongoing study, EGISTs appear to be histopathologically identical to GISTs. EGISTs arising from the omentum are very rarely reported, with only 57 previous cases in literature 1 2 4…”
