BAEZA-ZAPATA, Armando et al. Duodenal gastrointestinal stromal tumor: an uncommon cause of digestive tract bleeding. Endoscopia [online]. 2020, vol.32, n.2, pp.69-71.  Epub 18-Oct-2020. ISSN 2444-6483.  https://doi.org/10.24875/end.20000040.

Gastrointestinal stromal tumors (GIST) constitute most mesenchymal tumors of the gastrointestinal tract, only 5% can be found in the duodenum. Advances in the last 30 years in the field of molecular medicine, genetics, and immunohistochemistry have enabled to better identify this subgroup of tumors and facilitate specific treatment. We present the case of a 61-year-old male with melena and anemic syndrome in which an ulcerated GIST was found in the third portion of the duodenum with a favorable response to medical and surgical treatment.
