Resumen

RUESCA DOMINGUEZ, Cristina et al. Tumors of the duodenal gastrointestinal stroma. Rev.Med.Electrón. [online]. 2016, vol.38, n.3, pp.410-416. ISSN 1684-1824.

The tumors of the gastrointestinal stroma located in the duodenum are the most complex location for this neoplasia treatment; they are relatively infrequent, with a prevalence of 5 - 7 % of all the stromal gastrointestinal tumors surgically treated. Most of the reports published on these tumors are case reports. The clinical manifestations, the radiological diagnosis, the surgical treatment and the predictive factors are controversial matters. The malignant stromal gastrointestinal tumors are, in general, of great size (>5 cm), with a high mitotic index, and could give metastasis to the liver and peritoneum.  We report the case of a man aged 41 years with abdominal pain of sudden beginning. The echographic study showed complex lesion occupying the upper right hemi abdomen.  The abdominal tomography showed an increased uptake, heterogeneous, solid mass, in intimate contact with the duodenum. A laparotomy was carried out with a 20-cm tumor in intimate contact with the first duodenal portion, excising it.  The anatomopathological study revealed a low grade tumor with intestinal stroma characteristic cells. The surgical resection was completed.

Palabras clave : tumors of the gastrointestinal stroma; duodenum.
