Bladder inflammatory myofibroblastic tumor: report of four cases

Abstract

Abstract Background Inflammatory myofibroblastic tumor (IMT) of the bladder (BIMT) is a rare entity with non-specific symptoms and particular histological features. Though bladder location is very uncommon, it arises from the bladder submucosal stroma as a polypoidal growth and is easily mistaken clinically, radiologically and histologically with a malignant neoplasm. The main treatment is surgical resection. To our knowledge, few reports of this pathology have been duly informed in Latin America to date. Case presentation We present four case male patients evidencing bladder tumor initially treated with transurethral bladder resection, diagnosing BIMT. They had shown tumor recurrence and laparoscopic treatment were decided without evidence of new recurrence. Conclusion Due to the few reports of this pathology, specially in South America, it is important to know its therapeutic management and follow-up.
