Abstract:
Objective To analyze the clinical features of rectal and perianal inflammatory myofibroblastic tumor and evaluate its diagnosis and treatment.Method Clinicopathological data of 3 cases diagnosed as inflammatory myofibroblastic tumor from January,2005 to June,2011 were retrospectively reviewed.Results Inflammatory myofibroblastic tumor presents as infiltrative growth mass with rich vascularization on CT or MRI,and is difficult to distinguish from hemangioma and other rectal tumors.Preoperative biopsy usually fails to ascertain the entity of mass,and pathological examination of the whole resected specimen with immunohistochemical staining is needed to make final diagnosis.All 3 cases underwent sphincter preserving surgery.One case received a second radical operation 16 months after primary resection because of local recurrence.All patients are followed up to now,with a survival time of 67 months,55 months,and 35 months respectively.Conclusions Rectal and perianal inflammatory myofibroblastic tumor is difficult to diagnose on preoperative imaging examinations or biopsy.Immunohistochemical staining is needed to make final diagnosis.Sphincter preserving surgery with complete tumor removal could achieve long term survival.
