摘要To the Editor:Inflammatory myofibroblastoma (IMT) is a rare type of intermediate tumor with malignant potential that often affects children and young adults.Although IMT can arise from various organs,most originate in the lungs,abdomen/pelvis or retroperitoneum.These tumors are thought to arise via a benign inflammatory process,although some exhibit malignant behavior or undergo a malignant transformation.There are no uniform guidelines for the clinical management of IMT.[1,2] Currently,surgery is first choice of treatment,although other therapeutic options may be considered when total excision is not possible.[2,3] In this report,we summarize the clinical data of 16 patients aged ≤18 years who were diagnosed pathologically with IMT at our department between 2013 and 2018,review the literature and share our experiences with the diagnosis and treatment of this disease.
