Gastrointestinal stromal tumors are the most frequent mesenchymal neoplasm found in the gastrointestinal tract. In the last decades, molecular and immunohistochemical characteristics of gastrointestinal stromal tumors have been elucidated, allowing their differentiation from other neoplasms, an established diagnosis, therapeutic management, and prognosis. We describe a case of a 65-year-old man with an extraluminal gastrointestinal stromal tumor, diagnosed incidentally during a laparoscopic cholecystectomy. The tumor had a location in the greater curvature of the stomach. In the histopathological report the tumor had a smooth muscle differentiation, with the expression of the following markers: DOG-1, CD117, CD34, actin and H-Caldesmon. Before the laparoscopic cholecystectomy, a computed tomography was performed and no signs of tumor in the greater curvature were appreciated. The treatment of the gastrointestinal stromal tumors was surgical, avoiding the rupture of the tumor wall, which is associated with tumor recurrence in the future.
