Gastrointestinal Stromal Tumor of Small Intestine

The tumors of the gastrointestinal stroma were originally classified as other type of tumors (leiomyoma, leiomyobastoma or leiomyosarcoma) due to it similar histological appearance; however, the advances in the molecular biology and the immunohistochemistry have allowed its differentiation of other digestive neoplasms and to define them as an own clinical and histopathological entity. This is the case of a black female patient aged 79 presenting with abdominal pain during 3 days of evolution started in the right iliac fossa and then it remains in the low belly accompanied by vomiting, fatigue and weakness. She was operated on and is diagnosed with a stump acute appendicitis and of occlusive type en elderly without to rule out an adhesion occlusion. Carrying out the laparotomy it was found that this not-coagulating cavity was blood-free and also a stalked hemorrhagic tumor with movements towards the terminal ileum. Authors carried out its exeresis resecting approximately 5 cm of small intestine with a termino-terminal suture later. A significant cleaning of peritoneal cavity was carried out with the habitual closure achieving a satisfactory evolution with her discharge at 7 days. Patient remains asymptomatic at one a half year postoperative and biopsy yielded a 5 cm-small intestine tumor with a low grade of malignancy.
