[ XXXX of the small intestine. Apropos of 3 cases].

@entity5 @entity1822
The authors report three cases of @entity1822 of the small intestine and review the literature on this subject. @entity1822 of the small intestine are rare @entity5 , representing 0.2% of all @entity5 of the gastrointestinal tract. These large, round, hypervascular @entity5 are derived from smooth muscle cells in the intestinal wall and often develop extra-luminally. The malignant nature is often difficult to confirm on the histological examination. The clinical signs often only appear when the @entity5 has reached a large volume. It is rare to make the diagnosis pre-operatively, despite the use of a number of investigations. Arteriography is the most reliable examination. Spread of the disease is essentially haematogenous. The @entity5 invades adjacent organs, causes hepatic metastases and peritoneal seedlings and tends to recur locally. The treatment is essentially surgical and the prognosis varies according to the size of the @entity5 , its grade, its activity and its degree of extension. The 5-year survival of all forms of the disease varies between 20 and 50%, according to the series.
