The inflammatory myofibroblastic tumor behaves predominantly benign but can sometimes show varying degrees of aggressiveness. It is located in different organs, the lung is the most frequent, followed by the abdominal cavity. We present 2 cases of inflammatory myofibroblastic tumor. Case No. 1 female 5 years old with pale skin mucosa, anorexia, abdominal pain, fever, heart murmur, and hepatosplenomegaly. Ultrasound, CT and contrast radiological study: tumor in the stomach with thickening of their walls suggestive of lymphoproliferative disease. Endoscopic Study: warty lesion on greater curvature and high body. Biopsy inconclusive. Case No. 2 female 14 years with severe constipation, dominal pain, palpable mass in mesogastrium and hypogastric. Ultrasound and CT: space-occupying lesion in the mesentery, cystic. The two patients had severe anemia, leukocytosis and thrombocytosis. Laparotomy was performed in both Case No. 1: solid tumor greater curvature gastric resection was completed by partial gastrectomy. Case No. 2: tumor that arises from the transverse mesocolon, cystic, occupying the entire abdomen, 90% were resected. Pathological diagnosis: inflammatory myofibroblastic tumor. Satisfactory in both cases. This neoplasm should be suspected in children to prevent radical therapies, surgery, conservative treatment is sufficient in most cases.
