[Unusual location of an inflammatory myofibroblastic tumor: a case report].
Inflammatory myofibroblastic tumor is a rare lesion that is usually located in the lung. The most commonly reported extrapulmonary locations are the mesentery and the retroperitoneum. We report the case of an 8-year-old girl with an inflammatory myofibroblastic tumor in an unusual location. The patient was referred to our center for suspected complicated appendicitis. Abdominal ultrasonography detected ileoileal intussusception with a mass in the distal portion. Emergency laparotomy confirmed ileoileal intussusception secondary to an intraluminal tumor. Histologic study revealed the mass was an inflammatory myofibroblastic tumor. Inflammatory myofibroblastic tumors are rare mesenchymal masses usually found in children. When located in the abdomen, they can mimic malignant lesions like lymphomas, sarcomas, or metastases. The cause and prognosis of inflammatory myofibroblastic tumors are unknown.
