| description | Stromal tumors of the gastrointestinal tract (gists) represent relatively rare lesions that arise from connective tissue elements located along the entire length of the gut. They were initially identified by immunohistochemical investigation, proving their origin from nondifferentiated mesenchymal cells. Only a minority of this lesions, mainly those confined to the esophagus and rectum, have been shown to correspond to mature, well-differentiated types of neoplasms such as leiomyoma or leiomyosarcoma. The majority of gists corresponds to a heterogeneous group of lesions that have as their common denominator an immature proliferation of epithelioid or spindle cells arising from its muscle layers, or between them, showing partial or incomplete myoide, neural, ganglionic, or mixed features of differentiation. This case report intends to show a gist of small bowel in a male, 46 years old, with a two-year of evolution. |
