ABSTRACT

Introduction: The inflammatory myofibroblastic tumor is a rare condition, generally benign, with the possibility of malignancy. It is characterized by the mesenchymal proliferation of inflammatory cells, mainly lymphocytes, plasmatic cells and, occasionally, histiocytes. Objective: To publish a case report of a patient with an inflammatory myofibroblastic tumor. Case report: This is a 38-year-old female with a history of an uncomplicated peptic disease. Her first symptoms were weakness, dizziness, black stools, without weight loss; a laboratory finding of anemia. An endoscopy was performed, in which a polypoid, friable lesion with ulcerations and erosions was found. The endoscopic biopsy reported benign hyperplastic polyp. Subtotal gastrectomy was performed, undergoing gastrojejunal anastomosis and Roux-en-Y shunt, as well as omentectomy and resection of the ganglia of the lesser curvature. A transoperative histopathology exam reported a probable gastrointestinal stromal tumor (GIST). The final report was an inflammatory myofibroblastic tumor. Discussion: The inflammatory myofibroblastic tumor of gastric presentation is an uncommon entity; there are isolated case reports in the literature. The main symptoms, as in our case, can be manifested with high digestive hemorrhage and secondary anemia. It is necessary to differentiate these from gastrointestinal stromal tumors (GIST). Management requires complete resection, which in most cases is curative, with the disappearance of symptoms and other disorders. When the resection is incomplete, there may be a recurrence, which is more frequent within the first year. Conclusion: The inflammatory myofibroblastic tumor is an uncommon gastric neoplasm; a laparoscopic approach is possible, and it facilitates its diagnosis and management; therefore, it has become an appropriate option for patients with this rare pathology.
