title: Stromal tumor of the lesser omentum : a case report.
abstract: Gastrointestinal stromal tumors (GISTs) represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Extragastrointestinal stromal tumors (EGISTs), neoplasms with immunohistological features overlapping those of GISTs, are found in the abdomen outside of the gastrointestinal tract with no connection to the gastric or intestinal wall. We report the clinical, macroscopic and immunohistological features of an EGIST arising in the lesser omentum of a 58-year-old woman. This is a very rare location of intra abdominal stromal tumors.
