RESUMO
Although gastrointestinal stromal tumors (GISTs) are a rare type of cancer, they are the commonest mesenchymal tumors of the gastrointestinal tract (GIT). GISTs can affect any segment of the GIT, but the usual location is the stomach, followed by the small intestine. Surgical resection of the tumor is the gold standard treatment for localized GISTs, and in patients with inoperable and metastatic disease, imatinib mesylate is the standard treatment. Pathological diagnosis is based on morphology and immunohistochemical findings. We report the case of a 55-year-old man with jejunal GIST presenting with endophytic and exophytic growth, located in the proximal jejunum. He had history of melena, anemia and one episode of enterorrhagia, and was treated with surgical resection of the lesion. (AU)

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial tumors of the gastrointestinal tract. The most usual location is the stomach, followed by the small intestine, where it may cause digestive bleeding and anemia. Surgical resection of the tumor is the gold standard treatment, and definitive diagnosis is based on immunohistochemical analysis of the surgical specimen. We report the case of a 53-year-old man with gastric GIST presenting with endophytic and exophytic growth, located at the posterior wall of the stomach, in the antrum-body transitional zone, treated with gastric sleeve.
