[Rare digestive tumors: gastrointestinal stromal tumors (GISTs): about a case of small bowel location and literature review].

Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells. We here report a case of stromal tumor of the small intestine in order to analyze it in the light of literature data and imaging results, which may suggest prebiopsy diagnosis as well as its therapeutic and prognostic peculiarities.
